Choose a number x at random from the set of numbers {1, 2, 3, 4, 5}. now choose a number at random from the subset no larger than x, that is, from {1, . . ,x}. call this second number y. (a) find the joint mass function of x and y. (b) find the conditional mass function of x given that y = i. do it for i = 1, 2, 3, 4, 5. (c) are x and y independent? why?
