A mechanic for Mr. Plow makes minor repairs to snowplows during the winter. The snowplows break down at an average rate of 5 vehicles per day and breakdowns are distributed according to the Poisson distribution. The mechanic can service an average of 7 vehicles per day with a repair time distribution that approximates a negative exponential distribution. Assume an 8-hour day.


What is the expected average number of snowplows in the garage (waiting for repair and being repaired)?
