Consider independent trials, each of which results in outcome i, i = 0, 1, .,k, with probability Pi, where Eo Pi =1. Let N denote the number of trials needed to obtain an outcome that is not equal to 0, and let X be that outcome. (a) Find P(N = n), n 21 (b) Find P(X = j), j = 1,., k c) show that P(N=n, X=j) = P(N=n)P(X=j)
