Four cars arrive at an intersection on average per minute.
Assuming car arrivals occurs according to a Poisson process, answer
the following questions.
a. On average how much time will pass before the 6th
car arrives. Define the random variable.
b. The time that will pass before the 5th car arrives
is a random variable. Define the random variable. Compute the
variance of that random variable.

(9) Assume on average 10 passengers arrive per minute. Assuming poisson arrivals and departures, estimate the gain (if any) in ‘average time spent in system per passenger' if TSA decides to replace 4 type-A security scanners with 3 type-B security scanners. The service rate per scanner for type-A scanners is 3 passengers per minute and type-B scanners is 5 passengers per minute?

A car wash has one automatic car wash machine. Cars arrive according to a Poisson process at an average rate of 5 every 30 minutes. The car wash machine can serve customers according to a Poisson distribution with a mean of 0.25 cars per minute. What is the probability that there is no car waiting to be served?

Star Car Wash estimates that dirty cars arrive at the rate of 15 per hour all day and at the wash line, the cars can be cleaned at the rate of one every 4 minutes. One car at a time is cleaned in this example of a single-channel waiting line. Assuming Poisson arrivals and exponential service times, find the: (a) average time a car spends in the service system. (b) average number of cars in line. (c) average time a...

Cars arrive at a car wash at the rate of 18 cars per hour. Assume that cars arrive independently and the probability of an arrival is the same for any two time intervals of equal length. (2 pts.) Compute the probability of at least three arrivals in a 5-minute period. (2 pts.) Compute the probability of at most two arrivals in a 10-minute period.
