Suppose that the number of drivers who travel between aparticular origin and destination during a designated time periodhas a Poisson distribution with parameter μ = 20(suggested in the article \"Dynamic Ride Sharing: Theory andPractice\"†). (Round your answer to three decimal places.)
(a)
What is the probability that the number of drivers will be atmost 13?
(b)
What is the probability that the number of drivers will exceed26?
(c)
What is the probability that the number of drivers will bebetween 13 and 26, inclusive?
What is the probability that the number of drivers will bestrictly between 13 and 26?
(d)
What is the probability that the number of drivers will bewithin 2 standard deviations of the mean value?
