places. Do not round until your final calculation.
21. Bill and Sam are playing a game where they roll a die and
draw a card from a deck. What is the probability of rolling a 5
and then drawing a 5 from the deck of cards? Write your answer
as a fraction in lowest terms.
Use the formulas and to answer the following question:
22. Suppose on a particular day, the probability (among the
entire population) of getting into a car accident is 0.04, the
probability of being a texter-and-driver is 0.14, and p(car
accident or being a texter-and-driver)=0.15. Find the probability
a person was in a car accident given that they are a texter-and-
driver. Is this higher or lower than the probability among the
general population and why?

Remember the formula for expected value is: EV = Outcome1 *
Probability1 + Outcome 2 * Probability2… and so on.
23. You roll a die and win $1 if you get a 2 or 6, lose $2 if you
get a 3, win $5 if you get a 6, and lose $3 if you get a 1. What is
the expected value of this game? If you played the game
repeatedly, would you expect to win money? Why?
24. Suppose you are playing a game with two dice at a casino. If
you roll double ones, you win $1, if you roll double twos, you
win $2. This pattern continues, up to winning $6 for double
sixes. If you roll anything besides doubles, you lose $1. What is
the expected value of the game? Can you expect to win money
by playing this game repeatedly? *Hint: Find the total number
of outcomes of this game first. Only six outcomes win money.
The other outcomes lose money. You’ll find the expected value
with these outcomes. Good luck �

Introduction

· It is obvious that no matter which country education has its
own problems. Education is such a complex and important cause
that no country can provide perfect education. Every country is
striving to establish an education mechanism suitable for its
own national conditions. However, the shortcoming and
advantages of the American education system are still worth
explaining. What problems exist in the American education
system, and how to solve them? The main difference between
the education system in the United States and that in most other
countries is that the education system in the United States and
that in most other countries is that education in the United
States is for everyone in the society, not for few. The main
purpose of American education is to develop the talents of
every child, no matter how high or low he is, while instilling a
sense of citizenship in every child. Education in the United
States is mainly provided by the government, controlled and
funed by three levels of government-the federal government,
state government, and local government.
Body
· Education management in the United States is the
responsibility of the state or local government, not the coalition
government. However, the Federal Ministry of Education can
exert a certain degree of influence by controlling the education
fund. In elementary and secondary schools, the curriculum,
funding, teaching and other policies are determined by the local
district committee. School districts are usually separated from
other local affairs based on officials and budgets. Education
standards and standard tests are usually set by the government.
The American education system can be divided into four stages
as a whole, namely Pre-school Education, Elementary
Education, Secondary Education, and higher Education. From
pre-school education, elementary education to secondary
education, all belong to pre-college education, including
Nursery School and Kindergarten, Elementary School, Junior
High School, and High School.

· The biggest disadvantage of the American education system is
the unequal educational opportunities. Rich Americans can go
to private schools, but very poor Americans can only go to
public schools. Some schools will provide scholarships but most
Americans cannot afford tuition fees themselves. Another
problem is that public schools are often underfunded. Students
cannot read books because their school does not have a library,
and cannot take physical education classes because students
have no place to exercise and so on. In my opinion, the U.S.
government should pay attention to this issue because if
children have limited educational opportunities, their future
lives will be greatly affected. The advantage is that Americans
have many educational options. School choices include
privated, public, and professional. In addition, many American
schools also provide many extracurricular activities. For
example, sports, book clubs, internships, etc. These
extracurricular activities allow students to make friends or help
them apply for college in the future.

Barriers to Students Success
Historically, the black people in the United States have been
exposed to marginalization, exploitation, discrimination and
even prejudice on the basis of color. Additionally, having been
victims of slavery and all sorts of inhumane acts, most of the
black students have issues with regard to school achievement
and attainment. Different factors have been presented as to why
there exists disparities between the school success between the
white and the black question, with the core question revolving
around the possibility of bias of the white teachers. Therefore,
this research and exploratory essay will involve the analysis of
the question: Does the white teachers really have bias against
the black children towards their behaviors in school? Ideally,
although there has been the formation of movements for the
fighting of liberation of the black people, issues of racism,
inequality and even discrimination seem to be inevitable. The
teacher, in this case, play the central role in the prevalence of
bias, discrimination and the imposition of punishments on the
black students, barring them from desired educational

achievement.
Having been in school with black students, some issues are
reality as opposed to the assumed stories made by we, as the
white students. The ideologies presented by the earliest
scholars, for instance, equal but separate by Jim Crow, have
heightened disparities in the school set up. It is a war which
nobody is certain of its end, resulting in the suffering of school.
Although education has been introduced among the black
students, issues such as accessibility, affordability, quality and
the intensity of disciplinary measures imposed by the white
teachers. Additionally, policies such as the zero-tolerance have
also heightened the existence of disparities in the success of the
students, reducing the school attainment. When analyzing the
problem from the contemporary worldview, the teachers are the
core problem in the success of the black students, on the basis
of bias. Some of the studies have indicated that the words and
that statements made by the teachers hurt the black students,
whether done deliberately or even unconsciously.
Although most of us, that the white students, have little
experience of the suffering and the plights of the black people,
historical texts and writing help us familiarize with all these.
Ideally, the suppression of the suffering of black people has
taken a new dimension in the current world. For instance,
instead of having segregation laws, we have unequal
distribution of resources. Bias has been prevalent in the school
set-up, with the teachers playing the big role.
For years, most of the black students have been lagging behind
in terms of academic achievement when compared to their
counterparts, that is the white students. Reports presented by
the National Center for Education in the year 2014 indicate that,
statistically, the graduation rate for the white students was
approximately 83% while the black students were roughly 73%.
On the idea of test scores, the same disparity was realized. In
spite of the fact that there are other factors prompting such
disparity, the key problem has been associated with the biases
of the teachers and the administration at large. Anne Gregory, a

psychology professor at Rutgers University ascertains that
disparities have taken a new dimension, which can only be
blamed on the teachers.
In many cases, the differences in terms of treatment of the
students may not be malicious or even intentional. As a result,
it has been realized that some of the disparities are as a result of
cultural misunderstandings, while others have been termed as
implicit bias which is not intentional. Maryland University
Psychologist, Millie Killen has clearly stated that total
elimination of bias is inevitable. What this means is that people
have the role of avoiding acting on their biases. Reading and the
analysis of different resources has enabled me in the
understanding of the intensity of bias in the education system.
For instance, teachers in most cases hardly identify blacks’
students with outstanding academic achievement. For example,
according to the data presented by the study done by Early
Childhood Longitudinal, Sean Nicholson-Crotty together with
other colleagues realized that 54% of the black students were
less likely to receive the recommendation for programs which
are educated- gifted, when compared to the whites. Such
recommendations did not put into consideration aspects such as
the test scores which were standardized (Owens & McLanahan,
2019). On the contrary, in the event whereby the black students
had black teachers then they had high chances of getting
referrals for such programs.
From my own understanding and perception, expectations of the
teachers should be held accountable and responsible for such
disparities. Most of the white teachers do not expect black
students to excel more than the white ones. Additionally, Seth
Gershenson, from a university in America evaluations done by
both white and black teachers on the evaluation of ne black
student, 12% of the white teachers are likely to predict
completion of school by the black student, as well as 30%
prediction of the graduation possibility. When it comes to the
giving of feedback, for instance in essays, most of the white
teachers give more criticism on poorly written work by blacks

when compared to whites. This resource is essential for my
research in that it gives a clear guide on the excellence rates of
the white students when compared to the white ones. Moreover,
the low school attainment and performance of the black students
is attributed to biases in marking and the making of referrals,
especially when done by the white teachers.
Racial bias influences not only the teaching but also the
mannerism of discipline imposition on the students, as a result
of misbehavior. Data collected and presented by the department
of Education’s Office of the Civil Rights in the United States
back in 2013 and 2014 indicated that black students in the K-12
level received more suspensions when compared to the whites.
This does not necessarily mean that black students cause most
of the problems as noted by Gregory. Most of the studies done
have indicated that most of the white teachers take advantage of
the socioeconomic status, behaviors self-reported as well as the
reported behavior by other teachers for punishing the black
students. As a result, most of the punishments imposed on the
black students tend to be disproportional. Students suspended
from schools tend to drop out, and become run-ins in the
systems of juvenile justice (Bacher-Hicks, Billings & Deming,
2019). Repetition of this pattern, (that is suspension, dropping
out and juvenile cases) have resulted in the documentation of
various literatures, termed as the “school-to-prison pipeline.”
Reading these reports by researchers enabled me to realize that
most of the disparities and gaps in discipline can be done in a
subtle manner. Research done by psychologists from Stanford
University, that was Jennifer Eberhardt and her colleague Jason
Okonofua discovered that handling of cases of misbehavior by
the teachers is not influenced by the held stereotypes for that
particular group of people. These assertions only applied in the
first infraction, and indication that repeat of such behavior
incorporated the underlying stereotypes. For instance, in the
case of black students, description of troublemakers is used,
making the punishment be extremely harsh as a way of instilling
desired behavior. Implicit bias prompts teachers in making

assumptions that misconduct has direct correlation with
misbehavior. Therefore, they say that stereotyping of the blacks
as troublemakers and even violence is borrowed in cases of
misbehavior in schools (Gopalan & Nelson, 2019). On the other
hand, I say that imposition of punishment should be based on
facts, rather than summed up stereotypes and irrational
assumptions.
This article is essential for the study of the issue of bias due to
the presentation of well-researched and factual information.
Based on the ideologies presented by the researchers, there has
been clarity on the relationship between color and the
imposition of discipline in different levels. Despite the
effectiveness of the article in addressing the issues of bias in
discipline measures between the black and white students,
reactions of the students have not been included. For instance,
when black students realize that they are being suspended from
school due to misbehavior which is heightened by their color,
how do they take it? Do they become more violent when they
return to school? Or do they suppress the violent behavior
presumed to be possessed? On the other hand, do the white
students bother about the privileges they enjoy because of
color?
According to reports presented by the researchers in the Negro
Education Journal, higher rates of the suspension of the black
students exists. When these suspension rates are compared to
those of students from other ethnicities and races, cases of
blacks are still the highest. Analysis of the suspension data over
a period of three years was conducted for the explanation of the
school variability percentages on the black students in the
secondary schools in the urban parts. Analysis of the results in
backward hierarchy elimination showed that explanation for the
high percentages of suspension of the white students, the
increment of the school attainment and achievement
discrepancies between the black students and the white ones.
Variables used in the model and the percentages of the school
enrolment of the black students, instructional staff who were

blacks as well as the novice of the instructional staff hardly
give the prediction of the suspension possibilities of the black
students (Mitchell, M. M., Armstrong, G., & Armstrong, T.
2020). Therefore, the variations in the suspension rates of the
black students is dependent on unpredictable variables, for
instance, the race of the teacher.
This resource is crucial for my research topic in that it aids in
the explanation of the guidelines dictating suspension variables.
Additionally, I have also noted that suspensions are not prone to
the black students alone, but also includes the white ones as
well. This means that most of the variations are based on
tangible facts, rather than assumptions. Although most of the
black students tend to be more vulnerable to suspensions,
conformity to the set guidelines of the institutions mitigates the
occurrence of such chances. Ideally, variability of these rates of
suspension elaborate as to why there exists some correlation
between the percentages of the suspensions in the different
ethnicities and races in the United States.
Unfortunately, most of the early trainees of the black students
often identity and brand black boys as troublemakers at a very
early age. Walter Gilliam, directing the School of Medicine in
the Yale University, when directing Edward Zigler Center in the
Child Development as well as Social Policy documented the
cases of expulsions in the preschool. In the case of a child,
Walter Gilliam realized that there are three factors that made a
preschool child be more vulnerable in being kicked out of
school. These factors tend to be child-related and include the
following: being black, looking a little bit older when compared
to other classmates as well as being male. Moreover, studies
done by scholars and researchers, for instance, Phillip Atiba
Goff found out that students from the different racial
backgrounds, involved the overestimation of both the age
inclusive of the culpability (Anobile, Guerrini, Burr, Monti, Del
Lucchese & Cicchini, 2019). On the other hand, when
addressing the issue from the implicit bias perception, the
African American boys are not only culpable but also the most

dangerous, resulting in the imagination of high possibility of
suspension and expulsion from schools.
Resource is significant in the study in that it aids in
understanding that the marginalization and the stereotyping of
the black male gender starts at early stages. I find it hard to
believe how a preschool teacher can judge the violence or even
the vulnerability of extreme misbehavior at such an early age.
To some extent, I would argue that the teachers ought to be
accountable for such bias. Rationale for my assertion is based
on the fact that, at such an early stage, most of the behavior of
the child is learnt from the surrounding. Therefore, the question
of the role of school in shaping the desired behavior should be
put into consideration.
To conclude, from this exploratory research paper and essay, it
is evident that racial disparities in the schools are heightened by
the teachers. Issues of the magnitude of discipline, the academic
attainment and achievement is highly dependent on the race of
the teacher. As a result, cases of disparities and gaps seem
inevitable between the black and white students. As well, there
is evidence that black students disproportionately face harsh
discipline actions in the school, for instance suspensions or
even in and out of school suspensions. Punitive actions imposed
on the black students result in low academic achievement.
Rationale for this assertion is based on the fact that disciplinary
policies interfere with the time that the student could have spent
engaging in meaningful educational activities.
