First-time licensees are required to take a rules of the road computer exam and then are required to get behind the wheel and pass a driving exam. The driver's license office has only one computer test station and only driving test instructor. Licensees on average take 40 minutes to complete the rules of the road exam and 35 minutes on the physical driving portion. Assume Poisson arrivals and exponential process times with the first station utilized 100%. The waiting area to get onto the driving course can accommodate only 4 applicants.

2. How much is reduced from the case where there is no limit on the number of applicants in the waiting area?
