The modeling and solution of problems concerning motel reservation networks for motels were studied. Researchers defined a Type I call to be a call from a motel's computer terminal to the national reservation center. For a certain motel, the number, X, of Type 1 calls per hour has a Poisson distribution with parameter = 1.5. Complete parts (a) through (e) below. a. Determine the probability that the number of Type 1 calls made from this motel during a period of 1 hour will be exactly four. The probability that exactly four Type 1 calls are made is 0.0470. (Round to three decimal places as needed.) b. Determine the probability that the number of Type 1 calls made from this motel during a period of 1 hour will be at most two. The probability that at most two Type 1 calls are made is (Round to three decimal places as needed.)
