Question: Obtain the moment generating function of X and hence show that if R is another independent random variable with P(R = r ) = (e

Obtain the moment generating function of X and hence show that if R is another independent random variable with P(R = r ) = (e − 1)e−r for r = 1, 2, . . . , then R − X is exponentially distributed. (Oxford 1981F)
