Inquiries arrive at a recorded message device according to a Poisson process of rate 15 inquiries per minute. a. Find the probability that in a 1-minute period, 3 inquiries arrive during the first 10 seconds and 2 inquiries arrive during the last 15 seconds. b. Find the mean and variance of the time until arrival of the tenth inquiry.
