Let X be a discrete random variable with probability function f(x) = P(X= x) = (1-p)p-2 for x = 2, 3, 4, 5, .... for some 0 < p < 1. (a) Find P(X> 4). (b) Find P(X=3+x | X > 4) for x = 2, 3, 4.... and compare this with P(X = x). (c) Let R be the remainder when X is divided by 5 (so R is a random variable taking possible values
