unsuccessful keys

A man with n keys wants to open his door and tries the keys independently and at random. Find the mean and variance of the number of trials (a) if unsuccessful keys are not eliminated from further selections; (b) if they are. (Assume that only one key fits the door. The exact distributions are given in II, 7, but are not required for the present problem.)
