Messages arrive at an electronic mail server at the average rate of 4 messages every 5 minutes. Their number is modeled by a Binomial counting process. (a) What frame length makes the probability of a new message arrival during a given frame equal 0.05? (b) Suppose that 50 messages arrived during some 1-hour period. Does this indicate that the arrival rate is on the increase? Use frames computed in (a).

Vehicles have been arriving at a toll bridge at an average rate of 216 an hour. Only one toll booth is currently open and can process arrivals (collect tolls) at a mean rate of 20 seconds per vehicle. a. How many vehicles should be expected at the toll bridge in a 10-minute period? Please show how you arrived at your answer. b. Define X to be the number of vehicles arriving at the toll bridge in a 10-minute period and...
