A bank manager wishes to provide prompt service for customers at
the bank's drive-up window. The bank currently can serve up to 10
customers per 15-minute period without significant delay. The
average arrival rate is 7 customers per 15-minute period. Let
x denote the number of customers arriving per 15-minute
period. Assuming x has a Poisson distribution:
(a) Find the probability that 10 customers will arrive in a particular 15-minute period. (Round your answer to 4 decimal places.)
(b) Find the probability that 10 or fewer customers will arrive in a particular 15-minute period. (Do not round intermediate calculations for calculating probability. Round your answer to 4 decimal places.)
(c) Find the probability that there will be a significant delay at the drive-up window. That is, find the probability that more than 10 customers will arrive during a particular 15-minute period. (Do not round intermediate calculations for calculating probability. Round your answer to 4 decimal places.)

Willow Brook National Bank operates a drive-up teller window that allows customers to complete bank transactions without getting out of their cars. On weekday mornings, arrivals to the drive-up teller window occur at random, with an arrival rate of 30 customers per hour or 0.5 customers per minute. In the same bank waiting line system, assume that the service times for the drive-up teller follow an exponential probability distribution with a service rate of 36 customers per hour, or 0.6...

The average number of customers arriving at a drive-through window of a bank branch is 39 per hour during lunch hours. Use X to denote the number of arrivals in a 5 minute time interval. Assume the customers arrive independently and the number of arrivals within each 5 minutes follows a Poisson distribution. Keep at least 4 decimal digits if the result has more decimal digits.

A bank has one drive-up teller. The teller can serve at the rate of 11.2 bank customer in an hour. Customers arrive at the drive-up window on an average every 7.5 minutes. The bank is currently analyzing the possibility of adding a second drive-up window at an annual cost of $20,000. It is assumed that arriving cars would be equally divided between both windows. It is estimated that each minute’s reduction in customer waiting time would increase the bank’s revenue...
