21 The probability of a customer arrival at a grocery service counter in any one second is equal to 0.1. Assume that customers arrive in a random stream, so an arrival in any one second is independent of all others. (Round your answers to four decimal places.) (a) Find the probability that the first arrival will occur during the ninth one-second interval. (b) Find the probability that the first arrival will not occur until at least the ninth one-second interval.
