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 = 20 (suggested in the article "Dynamic Ride Sharing: Theory and Practice"). (Round you three decimal places.) (a) What is the probability that the number of drivers will be at most 187 (b) What is the probability that the number of drivers will exceed 297 (e) What is the probability that the number of drivers will be between 18 and 29, inclusive? What is the probability that the number of drivers will be strictly between 18 and 297
