Let X, Y, and Z be three i.i.d. geometric random variables with parameter p, i.e., the probability mass function of X is PX(k) = (1 − p) k−1p, k = 1, 2, . . .
Find the conditional probability distribution of X + Y given X + Y + Z, i.e., find: P(X + Y = i|X + Y + Z = j).

Let X be the random variable with the geometric distribution with parameter 0 < p < 1. (1) For any integer n ≥ 0, find P(X > n). (2) Show that for any integers m ≥ 0 and n ≥ 0, P(X > n + m|X > m) = P(X > n) (This is called memoryless property since this conditional probability does not depend on m.)
