Suppose the discrete random variables X and Y are jointly distributed according to the given table. a. Compute the expected values E(X) and E(Y ), the variances V (X) and V (Y ), and also the covariance Cov(X, Y ) of X and Y. b. Determine whether X and Y are independent. c. Let T = X − Y . Compute E(T) and V (T)
