What is the mean or expected number of customers that will arrive in a five- minute period? b. Assume that the Poisson probability distribution can be used to describe the arrival process. Compute: i. the probability that exactly 0 will arrive during a five-minute period ii. the probability that exactly 2 will arrive during a five-minute period c. Assume that the service times for the drive-thru window follow an exponential probability distribution with a service rate of 42 customers per hour. Use the exponential probability distribution to answer the following questions: i. What is the probability the service time is one minute or less? ii. What is the probability the service time is two minutes or less?
