Emergency 911 calls to a small municipality in Idaho come in at a rate of 6.9 calls every hour. Assume that the number of 911 calls is a random variable that can be described by a Poisson distribution. What is the probability of four 911 calls in the next hour? Round your answer three decimal places.

93. At a 911 call center, calls come in at an average rate of one call every two minutes. Assume that the time that elapses from one call to the next has the exponential distribution. Where appropriate, round answers to three decimal places (i.e. 0.123) a. On average, how much time occurs between five consecutive calls? Answer ____minutes b. Find the probability that after a call is received, it takes more than three minutes for the next call to occur....

to a call center where an automated machine can answer three calls in a five-minute period. Assume that calls occur at an average rate of 1.2 every five minutes. [Hint: Poisson Distribution A. Calculate the probability that no calls will occur during the next five minutes? B. Caleulate the probability that more calls (more than the system can handle) will occur during the next 5 minutes? (Hint: think of the complement!]
