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....
