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.)...
Cars arrive at a car wash randomly and independently; the probability of arrivalis the same for any two time intervals of equal length. The mean arrival rate is 15 cars per hour. (EXCEL) (a) What is the probability that 20 or more cars will arrive during any given hour of operation? (b) What is the mean time between arrivals? Why?

Compute the probability of no arrivals in a one-minute period (to 6 decimals) b. Compute the probability that three or fewer passengers arrive in a one-minute period (to 4 decimals) c. Compute the probability of no arrivals in a 15-second period (to 4 decimals) d. Compute the probability of at least one arrival in a 15-second period (to 4...

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...
A store has a car wash facility for cleaning service. The arrival rate of cars is 15 per hour. The average service time is 3 minutes. Assume that the cars arrive in a poisson process and the service time distribution is exponential. There is only one facility providing service, and the parking space is only enough for two cars. If there is no car, the arrival car will enter this store. If there is one car in the parking space,...

(1) Busy car wash Suppose you run a (busy) car wash, and the number of cars that come to the car wash between time 0 and time s > 0 is a Poisson process with rate λ = 1. The number of red cars that come to the car wash between time 0 and time s > 0 is a Poisson process with rate 2. The number of blue cars that come to car wash between time 0 and time...
Suppose small aircraft arrive at a certain airport according to a Poisson process with rate α = 8 per hour, so that the number of arrivals during a time period of t hours is a Poisson rv with parameter u= 8t. (Round youranswers to three decimal places.) (a) What is the probability that exactly 6 small aircraft arrive during a 1-hour period? What is the probability that at least 6 small aircraft arrive during a 1-hour period? What is...
A shop has an average of five customers per hour 5. A shop has an average of five customers per hour (a) Assume that the time T between any two customers' arrivals is an exponential random variable. (b) Assume that the number of customers who arrive during a given time period is Poisson. What (c) Let Y, be exponential random variables modeling the time between the ith and i+1st c What is the probability that no customer arrives in the...
Busy car wash Suppose you run a between time 0 and time s > 0 is a Poisson process with rate A = 1. The number of red cars that come to the car wash between time 0 and time s > 0 is a Poisson process with rate 2. The number of blue cars that come to car wash between time 0 and time s >0 is a Poisson process with rate 3. Both Poisson processes are independent of...
