The number of phone calls arriving at a switchboard can be represented by a Poisson random variable. The average number of phone calls per hour is 1.7. (a) Find the probability of getting a total of at least 3 phone calls in the next hour. (b) Find the probability of getting a total of at least 3 phone calls in the next two hours.

The number of calls arriving at a switchboard from noon to 1
p.m. during the business days Monday through Friday is monitored
for six weeks (i.e. 30 days). Let X be defined as the number of
calls during that one-hour period. The relative frequency of calls
was recorded and reported as:
Values 5 6 8 9 10 11 12 13 14 15

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...

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?
The probability mass function of the number of calls taken by a switchboard within 1 minute...
The probability mass function of the number of calls taken by a switchboard within 1 minute is given by the following table: xi (0 1 2 3 4 5 6) Pi (0.01 0.10 0.17 0.26 0.17 0.06 M) If the numbers of calls taken in two different minutes are independent, what is the expectation of the number of calls taken within one hour? Round your answer to the nearest hundredth. Then, 3.7 rounds to 3.70, and 3.742 rounds to 3.74
