Let's assume that the ratio of calls that enter a call center is 30 per hour. a) What is the probability that in a timeframe of 3 minutes, the call center receives no calls? b) What is the probability that in a timeframe of 5 minutes, the call center receives more than 5 calls?

Step 1
30 calls per hour = 30/60 calls per minute = 0.5 calls per minute Now, we can use the Poisson distribution formula to calculate the probability of receiving no calls in 3 minutes: P(X=0) = e^(-λ) * λ^0 / 0! where λ is the expected number of calls in 3 Show more…

The average rate of calls in a busy call center is 3 calls per 6 minutes. Then answer the following questions: a) What is the probability that at least 30 seconds will elapse before next call? b) What is the probability that exactly 10 calls will come in half an hour? c) Consider that you are the call center employee. You took a break for a tea and come back to your desk and 2 minutes have passed. What is the probability that you will wait more than 4 minutes after the end of your break?

Suppose calls are coming into a service center at an average rate of 3 per minute as a Poisson process. (a) What is the probability that no calls arrive time 0 to 2 minutes and at most two calls arrive between time 2 to 3 minutes? (b) What is the probability that the fourth call arrives within 30 seconds after the third call? (c) What is the probability that the fifth call takes more than 2 minutes to arrive?
