Suppose that in Problem 70 we continue to flip the coin until a head appears. Let N denote the number of flips needed. Find

Problem 70

Consider an urn containing a large number of coins, and suppose that each of the coins has some probability p of turning up heads when it is flipped. However, this value of p varies from coin to coin. Suppose that the composition of the urn is such that if a coin is selected at random from it, then the p-value of the coin can be regarded as being the value of a random variable that is uniformly distributed over [0, 1]. If a coin is selected at random from the urn and flipped twice, compute the probability that (a) The first flip results in a head;

(b) Both flips result in heads.
