An expressway off-ramp consisting of a single lane leads directly to a tollbooth. The rate of arrival of vehicles at the expressway can be considered to be Poisson with a mean of 50 veh/h. and the rate of service to vehicles can be assumed to be exponentially distributed with a mean of 1 min. What is the average number of vehicles waiting to be served at the booth.
