Assume that the number of telephone calls arriving at a switchboard by time t (minutes) is described by Poison process {N(t)}. On average, one call comes in every 10 minutes.
What is the probability that two or more calls will occur in 10 < t ≤ 20?

Calls arrive at Lynn Ann Fish's hotel switchboard at a rate of 1.5 per minute. The average time to handle each is 10 seconds. There is only one switchboard operator at the current time. The Poisson and negative exponential distributions appear to be relevant in this situation. a) The probability that the operator is busy = 0.25 (round your response to two decimal places). b) The average time that a caller must wait before reaching the operator = 0.06 minutes...
