109. Poisson Probability Between 5:00 PM and 6:00 PM, cars arrive at McDonald's drive-thru at the rate of 20 cars per hour. The following formula from probability can be used to determine the probability that x cars will arrive between 5:00 PM and 6:00 PM. 20'e-20 P(x) x! where x! = x • (x – 1) • (x – 2) ·....3·2-1 (a) Determine the probability that x = 15 cars will arrive between 5:00 PM and 6:00 PM. (b) Determine the probability that x = 20 cars will arrive between 5:00 PM and 6:00 PM.
