Suppose that X and Y are independent random variables. Define Z - max(X,Y). (a) Show, justifying your working, that the cdf of Z, Fz, can be written in terms of the cdf of X, Fx, and the cdf of Y, Fy, as F2(z) - Fx(z) Fy(z). Hint: Recall that Fz(z) - P(Z 0, and that the random variable y follows the uniform distribution with cdf Fy (y)-y on 0
