- G:26) Joe and Jill are selling fishing licenses in two separate booths located in different parts of the Edmonton Sportsmen Show. They expect to sell a total (between both of them) of 519 licenses over 20 hours (assume Poisson arrivals and that each of them will sell equal amounts). The average time needed to sell a fishing license is 1.7 minutes (assume negative exponential service time). How many minutes per hour, on average, (rounded to two decimals) should Joe expect to be idle?Customers arrive at a milk booth for the required service. Assume that the inter-arrival and service times are constant and are given by 1.2 and 3 time units, respectively. Simulate the system by hand computations for 18 time units.
