Question

Please answer part h.

Automobiles arrive at the drive-through window at the downtown Baton Rouge, Louisiana, post office at the rate of 2 every 10
minutes. The average service time is 1.0 minutes. The Poisson distribution is appropriate for the arrival rate and service times
are negative exponentially distributed.
a) The average time a car is in the system = 1.25 minutes (round your response to two decimal places).
b) The average number of cars in the system = 0.25 cars (round your response to two decimal places).
c) The average number of cars waiting to receive service = .00 cars (round your response to two decimal places).
d) The average time a car is in the queue = .25 minutes (round your response to two decimal places).
e) The probability that there are no cars at the window = .80 (round your response to two decimal places).
f) The percentage of the time the postal clerk is busy = 20 % (round your response to the nearest whole number).
g) The probability that there are exactly 2 cars in the system = .032 (round your response to three decimal places).
h) If a second drive-through window, with its own server, were added, the average time a car is in the system =
minutes
(round your response to two decimal places).
