Cars arrive at a car wash randomly and independently; the probability of an arrival is the same for any two time intervals of equal length. The mean arrival rate is 10 cars per hour. What is the probability that 15 or more cars will arrive during any given hour of operation?

Therefore, the probability is P=0.161.

Step-by-step explanation:

We know that cars arrive at a car wash randomly and independently; the probability of an arrival is the same for any two time intervals of equal length.  We calculate the probability that 15 or more cars will arrive during any given hour of operation.

We know that the mean arrival rate is 10 cars per hour ⇒ λ=10.

We use the Possion formula:

we get

Therefore, the probability is P=0.161.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
