Question 1 (7 points): The number of telephone calls arrives at a call center at an average 10 calls per hour. (a) What is the probability that there are exactly 15 calls in a period of two hours? (b) What is the probability that there are exactly 15 calls in a period of two hours given that 5 calls were received during the first hour?

Step 1
The Poisson distribution is commonly used to model the number of events occurring in a fixed interval of time or space. The formula for the Poisson distribution is: P(x; Ī») = (e^(-Ī») * Ī»^x) / x! Where: - P(x; Ī») is the probability of x events occurring in the Show moreā¦

The number of telephone calls that arrive at a phone exchange is often modeled as a Poisson random variable. Assume that on the average there are 10 calls per hour. (a) What is the probability that there are exactly 5 calls in one hour? (b) What is the probability that there are 3 or fewer calls in one hour? (c) What is the probability that there are exactly 15 calls in two hours? (d) What is the probability that there are exactly 5 calls in 30 minutes?

Two telephone calls come into a switchboard at random times in a fixed one-hour period. Assume that the calls are made independently of one another. What is the probability that the calls are made a. in the first half hour? b. within five minutes of each other?
