Question: QUESTIONS 39-40 refer to Sam’s 24 hour Pharmacy across the street from a large urban general hospital which on average receives about 4 requests per hour to fill prescriptions, around the clock.

The night pharmacist comes on duty at 11pm. What is the chance that he has to wait more than 20 minutes from the time he comes on duty for his first prescription request for the night?
