A program consists of two modules. The number of errors, X, in the first module and the number of errors, Y, in the second module have the joint distribution, p(0, 0) = p(0, 1) = p(1, 0) = 0.2, p(1, 1) = p(1, 2) = p(1, 3) = 0.1, p(0, 2) = p(0, 3) = 0.05. (a) Find the marginal distributions of X and Y (b) Find E[X] and E[Y] (c) Find Var(X) and Var(Y) (d) Find Cov(X, Y) (e) Find the correlation between X and Y.
