Calculate the probabilities for the following events.
(a) (2 points) Exactly seven customers arrive in a random 1-hour period.
(b) (4 points) No more than two customers arrive in a random 1-hour period.
(c) (4 points) At least three customers arrive in a random 1-hour period.

Pete's Market is a small local grocery store with only one checkout counter. Assume that shoppers arrive at the checkout lane according to a Poisson probability distribution, with an arrival rate of 9 customers per hour. The checkout service times follow an exponential probability distribution, with a service rate of 15 customers per hour. The manager’s service goal is to limit the waiting time prior to beginning the checkout process to no more than five minutes. Also the manager of...
