Multiply and divide numbers between 0 and 1Patryk Mamica
Multiplication and division with numbers between 0 and 1 were investigated. A chart was created showing the results of multiplying and dividing the number 5 by various fractions between 0 and 1. The chart illustrates that as the multiplying/dividing number decreases between 0 and 1, the answer to the multiplication decreases and the answer to the division increases, with the smallest multiplying/dividing number of 0.1 resulting in an answer of 0.5 for multiplication and 50 for division.
Multiplication is a way to add up multiples. It involves doubling, adding numbers to themselves, and counting by various increments like 5s and 10s. Mastering multiplication tables requires practice with timed tests and relating numbers to real world examples. Continued practice is important to learn multiplication facts.
Integer rules for addition, subtraction, multiplication and division are explained. When multiplying or dividing integers, if the signs are the same then the answer is positive, and if the signs are different then the answer is negative. When adding integers, if the signs are the same then the answer keeps that sign, but if the signs are different then it becomes subtraction and the answer takes the sign of the larger number. Several examples are provided to illustrate the rules.
This document discusses percentages and methods for calculating them. It defines what a percentage is, shows how to convert common percentages to fractions, and provides methods for calculating percentage of a number and percentage of a total. Examples are given for calculating percentages as well as finding the percentage that one number is of another total. Practice questions with answers are also included to reinforce the methods and concepts.
This document provides a lesson on solving one-step equations using addition and subtraction. It contains examples of using tape diagrams and algebraic methods to solve equations, as well as checking solutions using substitution. Students are given exercises to practice solving equations visually with tape diagrams or algebraically, and to identify and correct mistakes in example equations. The lesson emphasizes solving one-step equations and checking solutions.
This document discusses multiplication and provides examples of tricks and methods for solving multiplication problems. It defines multiplication as repeated addition and provides examples like calculating the number of legs on cats to illustrate. It discusses memorizing times tables from 1 to 12 and provides tricks for the 5 times table. Finally, it discusses the lattice method and using the distributive property to multiply larger numbers like 234 x 23 by multiplying digits individually and carrying numbers.
Multiplication is repeated addition. It involves multiplying a multiplier by itself a specified number of times to get the product. The order of the multipliers does not matter, so 5 x 2 is the same as 2 x 5. Multiplying any number by 1 leaves the number the same, since it is only being added once. Multiplying any number by 0 results in 0, because nothing is being added.

The activity section describes a group word scramble game called "Figure Me Out". The mechanics are explained: 1) Students are divided into groups, 2) Groups study scrambled letters to form a word, 3) Arrange letters in 1 minute, 4) Raise board with answer, 5) Correct groups earn points, 6) Highest scoring
The theoretical probability of rolling a sum of 10 when rolling two number cubes is 5/36.
There are 6 possible ways to roll a sum of 10: (1,9), (2,8), (3,7), (4,6), (5,5), (6,4).
There are 6 combinations that result in a sum of 10 out of the total possible combinations when rolling two number cubes, which is 6^2 = 36 possible outcomes.
Therefore, the theoretical probability is 5/36.
1. A negative binomial experiment consists of repeated trials that result in one of two outcomes (success/failure). It continues until a fixed number (k) of successes occur.
2. The probability of success (p) is constant across trials, which are independent. The number of trials (x) needed to achieve k successes follows a negative binomial distribution.
3. The document provides the notation and formula for the negative binomial distribution. It also gives examples of calculating the probability of achieving k successes in x trials under this distribution.
This document provides an introduction to counting and probability. It defines key terms like sample space, outcome, and event. It discusses counting problems like determining the number of combinations that can be made from various clothing items. Examples are provided to illustrate how to use the fundamental principle of counting and product rules to solve counting problems involving multiple independent choices. The document also introduces basic probability concepts like computing the probability of an event occurring using the ratio of favorable outcomes to total possible outcomes. Examples demonstrate calculating probabilities for coin tosses, dice rolls, and drawing balls from containers.
The document discusses experimental and theoretical probability. It provides an example of calculating the theoretical probability of having 2 girls in a family with 3 children. The theoretical probability is calculated as 1/4 or 25% since there are 4 possible combinations (BBB, BBG, GBB, BGG) and only 1 of those combinations results in 2 girls.
The lesson plan aims to teach students about estimating probability through playing cricket games.

Reimagining Your Library Space: How to Increase the Vibes in Your Library No ...Diana Rendina
Librarians are leading the way in creating future-ready citizens – now we need to update our spaces to match. In this session, attendees will get inspiration for transforming their library spaces. You’ll learn how to survey students and patrons, create a focus group, and use design thinking to brainstorm ideas for your space. We’ll discuss budget friendly ways to change your space as well as how to find funding. No matter where you’re at, you’ll find ideas for reimagining your space in this session.
2. What are examples of a binomial experiment?
• I shoot 50 free-throws. How many do I make?
• A mother has 7 babies. How many are girls?
• I flip a coin 25 times. How many are heads?
• I call 100 phone #s from the phone book. How many people pick up?
• Each trial results in adding 1 or adding 0 to the total
• The probability of “success” does not change from one trial to the next
3. Guess which ones are binomial experiments
• 150 people play roulette. How many of them win?
• We ask 10 people at random to do 20 pushups. How many of them can do it?
• We ask 10 at random people to do 20 pushups. How many total pushups get
done?
• 30 random people go to Baskin Robbins. How many order vanilla?
• Each trial results in adding 1 or adding 0 to the total
• The probability of “success” does not change from one trial to the next
4. Guess which ones are binomial experiments (part 2)
• 150 people play roulette. How much money do they win?
• 150 people play poker. How many of them leave the table having lost $$?
• We select 10 people at random and measure their height. What is the average
height?
• We select 10 people at random and measure their height. How many people
are over 5’ tall?
• Each trial results in adding 1 or adding 0 to the total
• The probability of “success” does not change from one trial to the next
5. Guess which ones are binomial experiments (part 3)
• 𝑛 students play a game of trying to thread 21 beads onto a stick.
How many of them will succeed in under 1 minute?
• Each trial results in adding 1 or adding 0 to the total
• The probability of “success” does not change from one trial to the next
That’s today’s experiment
6. Why do we like binomial experiments?
Because binomial experiments have a formula for calculating the
probability of getting a certain result:
𝑃 𝑋 = 𝑥 =
𝑛
𝑥
⋅ 𝑝𝑥
⋅ 1 − 𝑝 𝑛−𝑥
where…
𝒙 is the number of “successes” in the experiment
𝒏 is the number of trials in the experiment
𝒑 is the probability of success in each trial
7. What is 𝑛
𝑥
????
𝑃 𝑋 = 𝑥 =
𝑛
𝑥
⋅ 𝑝𝑥
⋅ 1 − 𝑝 𝑛−𝑥
𝑛
𝑥
=
𝑛!
𝑛 − 𝑥 ! ⋅ (𝑥!)
But if you don’t feel like calculating it the long way, there is a
function in your calculator to calculate it
9. Using the binomial formula
For example, if it’s true that a coin is fair, what is the probability
that I get 9 heads out of 10 flips?
where…
𝒙 is the number of “successes” in the experiment = 𝟗
𝒏 is the number of trials in the experiment = 𝟏𝟎
𝒑 is the probability of success in each trial = 𝟎. 𝟓
𝑃 𝑋 = 𝑥 =
𝑛
𝑥
⋅ 𝑝𝑥
⋅ 1 − 𝑝 𝑛−𝑥
𝑃 𝑋 = 9 =
10
9
⋅ 0.59
) ⋅ 1 − 0.5 10−9
= 0.009765625
10. Our binomial experiment
• 𝑛 students play a game of trying to thread 21 beads onto a stick.
How many of them will succeed in under 1 minute?
. RULES .
• Move one bead at a time
• Keep the stick vertical

15. mean 𝑥 = 𝑛 ⋅ 𝑝
HINT: If 𝑥 refers to a Binomial(𝑛, 𝑝) random variable, then
𝑠𝑑 𝑥 = 𝑛 ⋅ 𝑝 ⋅ (1 − 𝑝)
You must replace 𝒏 and 𝒑
with VALUES and calculate.
What are our values for 𝒏
and 𝒑???
17. HINT:
If our class value of 𝑥 was 17, we
would write = 17 in those fields
and the bar would highlight red
Draw this histogram (with
highlighted bar) include
numbers and everything
18. 𝑃 𝑋 = 𝑥 =⋅
𝑛
𝑥
𝑝𝑥
⋅ 1 − 𝑝 𝑛−𝑥
You must plug our values for 𝒙, 𝒏, 𝒑 into the below formula.
Show your work.
where…
𝒙 is the number of “successes” in the experiment
𝒏 is the number of trials in the experiment
𝒑 is the probability of success in each trial
19. HINT:
If the 80% was the real proportion of people who can do the bead game
in less than 1 minute, where would we expect our class value for 𝑥 to fall
on the histogram we made?
In the tails of the histogram? In the center?
Now where did our class value actually fall? Did it match what we
expected?
20. HINT:
Based on our where our class’ number of successes 𝑥 fell on the
histogram, do you think the game should be made harder or easier or
kept the same? In order so that 80% of people can complete the task in
time (and thus 20% are unable to complete the task in time).
What can they do to make the game harder/easier?
