Answer 1

Answer:Cars enter a car wash at a mean rate of 4 cars per half an hour. 

Explanation:

Answer 2

The probability that, in any hour, exactly 22 cars will enter the car wash will be 0.0920.

What is probability?

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.

Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

The  mean rate of car is,$\rm \lambda = 66 \ car/hour$

$P(x=K) = \frac{8^k e^{-8}}{k\!}\\\\P(x=22) = \frac{66^{22} e^{-22}}{22\!}\\\\ P(x=22)=\frac{0.000000000000691\times 1.07\times 10^{40}}{22} \\\\\ P(x=22)=0$

Hence the probability that, in any hour, exactly 22 cars will enter the car wash will be 0
