Problem 3-15 (Algorithmic) Telephone calls arrive at the rate of48 per hour at the reservation desk for Regional Airways. (a) Findthe probability of receiving 6 calls in a 5-minute interval. Ifrequired, round your answer to four decimal places. f(6) = (b) Findthe probability of receiving 8 calls in 15 minutes. If required,round your answer to four decimal places. f(8) = (c) Suppose thatno calls are currently on hold. If the agent takes 4 minutes tocomplete processing the current call, how many callers do youexpect to be waiting by that time? If required, round your answerto one decimal place. Number of callers = What is the probabilitythat no one will be waiting? If required, round your answer to fourdecimal places. The probability none will be waiting after 4minutes is . (d) If no calls are currently being processed, what isthe probability that the agent can take 2 minutes for personal timewithout being interrupted? If required, round your answer to fourdecimal places. The probability of no interruptions in 2 minutes is.
