4.7 Jointly Distributed Discrete Random Variables
Joint Probability Distribution
Let X and Y be a pair of discrete random variables. Their joint probability distribution expresses the
probability that simultaneously X takes the specific

Many of the concepts and results from discrete random variables also apply for continuous random
variables.
