= Let X and Y have the joint pmf defined by f(0,0) = f(1, 2) = 0.2, f(0, 1) = f(1, 1) = 0.3 (and f (x, y) = 0 elsewhere). (a) Represent the joint probability mass function by a table. (b) Give the marginal probability mass functions of X and Y in the “margins” of the table in (a). p. (c) Compute jx, My, o, o, Cov(X,Y), and (d) Tabulate the conditional probability mass function of Y given X = 1. (e) Tabulate the conditional probability mass function of X given Y = 0. =
