A hospital anguish about queue in emergency rooms. The medical staff on hand cannot accommodate the patient on-queue if there are more than 10 emergency cases in a given hour. It is assumed that patient arrival follows a Poisson process, and historical data suggest that, on the average, 5 emergencies arrive per hour. What is the probability that more than 20 emergencies arrive during a 4-hour shift?
