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 cars per hour. What is the probability that or more cars will arrive during any given hour of operation (to 4 decimals)?

Step 1
Let's assume it as λ (lambda). The number of cars arriving at the car wash in any given hour follows a Poisson distribution. The probability mass function of a Poisson distribution is given by: P(X=k) = (λ^k * e^-λ) / k! where: - P(X=k) is the probability of k Show more…

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 15 cars per hour. What is the probability that 20 or more cars will arrive during any given hour of operation?

Cars enter a car wash at a mean rate of 2 cars per half an hour. What is the probability that, in any hour, exactly 4 cars will enter the car wash? Round your answer to four decimal places.
