(a) Suppose (X,Y) is a pair of continuous random variables with joint probability density function fx,x(s, t) = { 3e if s > 0 and t > 1 if not 3 t2 (b) Let Fx,y be the joint cumulative distribution function of the pair (X, Y). Compute Fx,y(4, 5). Let (X, Y) be as in Part (a). The random variable log(Y) has an exponential distribution. What is the corresponding rate parameter?
