5. (10%) a) Let X be a random variable. Suppose that E[X] = 3 and E[X2] = 9. Find EX) and justify your answer. b) Let X, Y be two independent random variables, each of which takes on values from {0,1). Suppose that for their joint p.m.f. p(x,y), it is already known that p(0,0) = 0.08 and p(1,1) = 0.48. Find p(0,1) and p(1,0) and justify your answer.
