Automobiles amve at the drive-through window at the downtown Baton Rouge, Louisiana, post office at the rate of 4 every 10 minutes. The average service time is 1.0 minutes. The Poisson distribution is appropriate for the arrival rale and service times are negative exponentially distributed. a) The average time a car is in the system = minutes (round your response to two decimal places) b) The average number of cars in the system = cars (round your response to two decimal places). c) The average number of cars waiting to receive service = cars (round your response to two decimal places). d) The average time a car is in the queue = minutes (round your response to two decimat ptaces). e) The probability that there are no cars at the window = (round your response to two decimal places) f) The percentage of the time the postat cleik is busy =40% (round your response to the nearest whole number) g) The probability that there are exactly 2 cars in the system =096 (round your response to three decimal places) 7i) If a second dive-through window, with its own sorver, were added, the average time a car is in the system: minutes (round your response to two decimal places)
