This document discusses various probability distributions including binomial, Poisson, and normal distributions. It provides examples of how each distribution can be used to model real-world scenarios involving probability. The binomial distribution describes experiments with two possible outcomes, like coin flips. The Poisson distribution models rare, independent events that occur randomly over time. The normal distribution approximates many natural phenomena and test scores due to the central limit theorem.

If we measure a random variable many times, we can build up a distribution of the values it can take.
Imagine an underlying distribution of values which we would get if it was possible to take more and more measurements under the same conditions.
This gives the probability distribution for the variable.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
9. The relative frequency of
occurrence of an experiment
outcome when repeating the
experiment.
The concept of probability is also used
in biostatistics.
17. Binomial distribution
If an experiment is repeated ‘n’ times then the
binomial distribution can be used to determine
the probability of obtaining exactly x success in
the ‘n’ number of trials.
18. • Outcomes are dichotomous-
• Only two outcomes are possible
out of n trial.
• One outcome is termed as
success
• and the other is failure.
Properties of binomial experiment
19. Properties of binomial experiment
• The experiment consist of n repeated
trials.
• The probability of success is same [
constant ] on every trial.
• Trial are independent [ outcome of
one trial does not effect the outcome
of the other.
20. Problem
• Six babies were delivered in the labour ward
of a hospital. Assuming equal probability for
male or female babies.
• A. two male babies.
• B. at least two male babies.
21. Solution
• X is number of male babies.
• P = occurrence of male babies divided by total
occurrence = ½
• There q= 1-p = 1- ½ = ½
22. A.
• P = two male babies x=2
• 6C2 = 6 x 5 = 30/2 = 15
1x 2
= 6 C2 [ ½]2 [1/2]6-2
= 15 x ¼ x 1/16 = 15/64
= 0.234
23. B at least two male babies
• 1- atmost one male baby
• 1- [ f(0) + f (1) ]
• 6C1 = 6/1 =6 6C0 =1
• 1- [ f(0) + f (1) ] = 1- [ 6C0[1/2]0 [1/2]6-0
+
[ 6C1 [1/2]1 [1/2]6-1
= 1- [1 x 1 x 1/64 ] + [ 6 x ½ x 1/32 ]
= 1- [1/64 + 1/64 ] = 1- 7/64 = 57/64= 0.891
= 0.891
25. Poison distribution
• It is called as law of small numbers.
• The number of occurrences of an
event that seldom happens but has
many opportunities to happen.
• it takes non negative integer values.
26.
27. • It is unimodal
• It exhibit positive skew that decrease as λ
decreases.
• The variance spread increases as λ decreases.
• Only data required to use poison distribution
is the mean number of occurrence.
• Poison resembles binomial if the probability of
an event is very small.
Poison distribution
28. Application of poison distribution
• It involves counting the number of times a
random event occurs in a given amount of
time.
• Example :
• Number of patients entering the hospital
during a specified time period.
29. Normal or Gaussian distribution
• Central limit theorem
• It states that when a large number of random
variables are independently and identically
distributed with finite variance , their sum is
approximately normally distributed.
30. It is the most important
continuous probability
distribution.
Normal or Gaussian distribution
31. • The behavior of many of the real life
situation can be modeled as normal
distribution.
• Example
• Monthly salary of a employees in a
locality
• Marks of the students in entrance test.
Normal or Gaussian distribution
32. • The data will follow a bell shaped
distribution is called a normal or
Gaussian distribution.
• Data around a central value or the
observation around the mean such a
distribution is called a standard or
normal distribution.
Normal or Gaussian distribution
33. The curve is called normal because
it is the usual distribution of
frequencies in nature when the
number of observation is
extremely large and the class
interval is very small.
Normal or Gaussian distribution
34. • The graph depends on the mean and
standard deviation
• The mean will show the location of
center of the graph
• Standard deviation determines the
height and width of the graph.
Normal or Gaussian distribution
