Question: A car was machine washes each car in 5 minutes exactly. It has been estimated that customers will arrive according to a Poisson distribution at an average of 8 per hour. Calculate:
1) Expected average time ( in minutes) a customer spends at the station
2) Average number of cars in the station ( both in line and being washed)
