Suppose that the number of drivers who travel between a particular origin and destination during a designated time period has a Poisson distribution with parameter μ = 20 (suggested in article "Dynamic Ride Sharing: Theory and Practice," J. of Transp. Engr., 1997: 308-312). What is the probability that the number of drivers will: (i) Be at most 10? (ii) Exceed 20? (iii) Be between 10 and 20, inclusive? (iv) Be strictly between 10 and 20?

Suppose a radioactive source is metered for 3 hours, during which time the total number of alpha particles counted is 328. Modeling the problem using a Poisson distribution, what is the probability exactly four particles will be counted in the next 2 minutes? Answer the question in two ways: (a) By defining X to be the number of particles counted in 2 minutes (b) By defining X to be the number of particles counted in 1 minute. Give your answers in decimal form with at least 6 significant figures.
Suppose that during lean hours in a call center, the number of calls received during any specified time period follows a Poisson distribution and, on average, the call center receives 20 calls in a hour. 1.What is the probability that there will be 25 calls in a 1 hr interval during lean hours? 2.What is the probability that there will be at least 1 call received in a 15 min interval during lean hours?
Workers at Lyman Limited arrive at work at an average rate of 8 workers per hour. Assuming the arrival times follow a Poisson distribution, calculate the probability that a manager will observe: a) exactly 6 workers arriving in a given hour. b) at least 2 workers arriving in a 15-minute period.
On average, Nancy has noticed that 27 trucks pass by her apartment daily (24 hours). In order to find the probability that more than 2 trucks will pass her apartment in a 4-hour time period using the Poisson distribution, find the average number of trucks per 4 hours. Round your answer to three decimal places, if necessary.
On average, Nancy has noticed that 21 trucks pass by her apartment daily (24 hours). In order to find the probability that more than 1 truck will pass her apartment in a 2-hour time period using Poisson distribution, find the average number of trucks per 2 hours.
Consider the previous question above, A further study determined that cars arrive to this shopping center according to a non-stationary Poisson process. The mean arrival rate increases linearly from 0.17 to 0.49 cars per minute between 10 am and 2 pm. Then the rate remains constant at 0.49 cars per minute between 2 pm and 4 pm. Finally, the rate changes to a constant 0.33 cars per minute between 4 pm and 5 pm. What is the probability that 60 cars will arrive between 1:45 pm and 4:15 pm?
A call center agent receives an average of 28 calls per hour. Assuming that this follows a Poisson distribution, use the normal approximation to determine the probability that in an hour, the call center agent will receive: a. 32 or more calls.b. greater than 25 calls. c. exactly 44 calls.
A certain kind of sheet metal has, on average, 5 defects per 15 square feet.Assuming a Poisson distribution, find the probability that a 25 square foot metal sheet has at least 9 defects. Round your answer to three decimal places.
A call center agent receives an average of 28 calls per hour. Assuming that this follows a Poisson distribution, use the normal approximation to determine the probability that in an hour, the call center agent will receive: 32 or more calls. greater than 25 calls. exactly 44 calls.
From past experience, it was found out that in a certain factory, there is an average of two accidents per' month. Assuming a Poisson distribution, determine the probability that in a certain month selected at random there would be:no accident;exactly two accidents;less than four accidents.
