4. Let X and Y have the joint pmf defined by f(0,0) = f(1, 2) = 0.2, ƒ(0, 1) = f(1, 1) = 0.3 (and f(x, y) = 0 elsewhere). %3D (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). (c) Compute µx, µY , ox, oỷ, Cov(X,Y), and (d) Tabulate the conditional probability mass function of Y given X = 1.
