Cars arriving for gasoline at a shell station follow a poisson distribution with a mean of 9 per hour. a. determine the probability that over the next hour, only one car will arrive. probability = b. compute the probability that in the next 6 hours, more than 22 cars will arrive.

Step-by-step explanation:

Given

Poisson Distribution with mean of 9 per hour

Mean of Process

Probability that over the next hour , only one car will arrive

Probability is given by

For k=1 and t=1

(b) For next 6 hours , more than 22 cars will arrive will be given by

k=22, t=6 hr

2 x t divided by n
