What is the expected number of idle tellers? - Queuing Theory Problem - Please solve parts a.) and b.) and show all the steps to get to the final solution(s).A small gas station has one gas pump to fill gas. Cars arrive according to a Poisson process at a mean rate of 15 cars per hour. Service time at the pump has an exponential distribution with a mean of 3 minutes. The small gas station only can park 5 cars (including the one at the pump). If a car cannot park, it will go to other gas stations. a.) What is the chance that the waiting line will be longer than 3? b.)
