13.1 Overview
13.1.1 Conditional Probability
If E and F are two events associated with the same sample space of a random experiment, then the conditional probability of the event E under the condition that the event F has occurred, written as P (E | F), is given by

13.1.2 Properties of Conditional Probability

13.1.3 Multiplication Theorem on Probability

13.1.4 Independent Events

13.1.5 Partition of a Sample Space

13.1.6 Theorem of Total Probability

13.1.7 Bayes’ Theorem
If E 1 , E 2 ,…, E n are mutually exclusive and exhaustive events associated with a sample
space, and A is any event of non zero probability, then

13.1.8 Random Variable and its Probability Distribution
A random variable is a real valued function whose domain is the sample space of a random experiment.
The probability distribution of a random variable X is the system of numbers

13.1.9 Mean and Variance of a Random Variable

13.1.10 Bernoulli Trials
Trials of a random experiment are called Bernoulli trials, if they satisfy the following
conditions:
(i) There should be a finite number of trials
(ii) The trials should be independent
(iii) Each trial has exactly two outcomes: success or failure
(iv) The probability of success (or failure) remains the same in each trial.
