Consider a bank with two tellers. Three people, Anne, Betty and Carol enter the bank at almost the same time and in that order. Anne and Betty go directly into service while Carol waits or the first available teller.

(b) What is the expected total time until the last of the three customers leaves?
(c) What is the probability for Anne, Betty, and Carol to be the last one to leave?
