Joint probability examples with solutions
Nettet6/252. 0. 0. This table is called the joint probability mass function (pmf) f(x, y) of ( X, Y ). As for any probability distribution, one requires that each of the probability values are nonnegative and the sum of the probabilities over all values of X and Y is one. That is, the function f(x, y) satisfies two properties: NettetDefinition 5.1.1. If discrete random variables X and Y are defined on the same sample space S, then their joint probability mass function (joint pmf) is given by. p(x, y) = P(X = x and Y = y), where (x, y) is a pair of possible values for the pair of random variables (X, …
