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 random variable x is the number of the number of calls received by a switchboard. Suppose x follows a Poisson distribution and the average number of occurrences in 20 minutes is 2. (1) What is the probability that between 10:00 and 10:30 the switchboard will receive exactly 5 calls? (2) What is the probability that between 10:00 and 10:30 the switchboard will receive more than 2 calls but fewer than 6 calls? Need Help

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:

The switchboard operator in a large law office receives calls at a rate of 100 per hour according to a Poisson distribution. The average time required to process a call is 30 seconds, exponentially distributed. Assuming that the single-server waiting line model applies, answer the following questions. A. What percentage of the time is the operator busy? B. What is the average time required until the operator answers a call? C. What is the average number of calls waiting to...
