The number of customers arriving per hour at a certain automobile service facility is assumed to follow a Poisson distribution with mean λ = 6. (a) Compute the probability that more than 20 customers will arrive in a 3-hour period. (b) What is the probability that the number of customers arriving in a 2-hour period will not exceed 40? (c) What is the mean number of arrivals during a 4-hour period?

The number of customers arriving at a local business every 15 minutes is 3. Supposing the arrival of customers follows a Poisson distribution, answer the following questions: What is the probability that exactly 5 people arrive in the next 15 minutes? What is the probability that at least 4 people arrive in the next 15 minutes? Probability that between 2 and 6 people arrive inclusive? Expected number to arrive in the next hour? Expected number to arrive in an 8 hour...
The number of customers entering a store on a given day is Poisson distributed with mean...
The number of customers entering a store on a given day is Poisson distributed with mean 150 . The amount spent in the store by a customer is exponential with mean 200. The amount spent is independent from number of customers . Estimate the probability that the store takes in at least $20,000. Leave the answer in terms of the distribution of he standard normal random variable.
Customer arrives at a grocery store to checkout counter according to a Poisson process with rate...
Customer arrives at a grocery store to checkout counter according to a Poisson process with rate per minute. Each customer carries a number of items that is uniformly distributed between 1 and 40. The store has 2 checkout counters, each capable of processing items at a rate of 15 per minute. To reduce the customer wait in queue, the store manager considers dedicating a one of the two counters to customers with x items or less and dedicating one of...
