Simulation--Homework Problem
“Eat at Joe’s” has decided to add a drive-up window to their restaurant. Due to limited
capital, there is only enough space for two (2) cars in the drive-up window lane (one
being served and one waiting). Joe would like to know how many customers are bypassing his restaurant due to the limited space in the drive-up window lane. Simulate ten
(10) cars as they attempt to use the drive-up window using the following distributions and
random numbers.
