Consider a sequence of independent Bernoulli trials, each with success probability p. Let X1 be the number of failures preceding the first seccess, and let X2 be the number of failures between the first two successes. Find the joint density of <X1,X2>.(note: X1 and X2 are called "waiting times") (p.313 #7 from first course in probability_Ross)
