Question 8 1 pts Let X and Y be two discrete random variables. It is known that the marginal pdfs of X and Y satisfy P(X = -4) = P(X = -2) = P(X = 2) = P(X = 4) = = and P(Y = -2) = P(Y = -1) = P(Y = 1) = P(Y = 2) = It is also known that the joint pdf of x and y satisfies P(X = -4, Y = 1) = P(X = 4, Y = -1) = P(X = 2, Y = 2) = P(X = -2, Y = -2) = 1. Then which of the following statements is FALSE? O Cov (X, Y) = 0. O E(X) = 0. O E(XY) = 0. O X and y are independent random variables
