      Conditional distribution is all about reducing the space of interest from the Sample space . to . the conditioning event. P( A | B ) = = (if each simple event is equally likely to happen) Conditional Probability: The conditional probability of A given that event B has occurred is . Ex.

      4.2 Conditional Probability. When working with more than one random variable at a time, we need to consider conditional probabilities. First, for discrete variables, the probability of xi occurring given that yj has occurred is called the conditional probability and is denoted P(xi|yj). The vertical bar denotes “given”.

      We could either use the joint probability mass function or conditional probability mass functions. We have two similar methods to describe two or more continuous random variables, namely the joint probability density function and conditional probability density functions. ... where FS(t) and FT(t) are the cummulative distribution functions of S ...

Understand the conditional probability of A given B as P(A and B)/P(B), and interpret independence of A and B as saying that the conditional probability of A given B is the same as the probability of A, and the conditional probability of B given A is the same as the probability of B.
