Web6/252. 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: WebLike single pmf, joint pmf has to be positive, and add up to 1: p (x, y) 0 and p (x, y) = 1 Events: sets consisting of elements (x, y). Examples: A = {(x, y): x + y = 5} B = {(x, y): …
