Continuation.

(a) Let R be the number of successive turns up to the th success (that is, the th success occurs during the Rth turn). Find E(R) and Var (R). Prove that P{R } p'q1| = v-1

(b) Consider two sequences of Bernoulli trials with probabilities P, 91, and p2, 92, respectively. Find the probability that the same number of turns will lead to the Nth success.
