During the holiday season, the airline "Volair" receives more calls than usual. The airline is forced to extend its hours of service and have two employees to answer and route the night calls to the appropriate departments. One is responsible for answering reservation calls, and the other handles claims calls. At this schedule, reservation calls arrive at a rate of 24 calls per hour while claims calls arrive at a rate of 10 calls per hour. It is assumed that the calls received for reservations are independent of those received for claims.

The probability distribution that best describes the number of reservation calls received in a given time interval is : a) The binomial distribution b) Poisson distribution c) Geometric distribution d) The negative binomial distribution e) The exponential distribution

The probability of receiving at least 2 calls for reservations during 5 minutes is : a) Close to 30%. b) Between 35% and 40 c) Between 40% and 45 d) Between 45% and 55%. e) Nearly 60%.

The probability of not receiving any claim calls for 5 minutes is : a) Nearly 0% b) Between 35% and 40 c) Between 40% and 45 d) Between 45% and 55 e) Close to 60%.

During a 12-minute period, the probability of receiving exactly 3 reservation calls and 3 reservation calls and 3 claim calls is : a) Between 0% and 5 b) Between 5% and 10 c) Between 10% and 15 d) Between 15% and 20%. e) More than 20%.

A reservation call has just been received, the probability that it will take 5 minutes or more to receive the next reservation call is a) Between 0% and 5 b) Between 5% and 10 c) Between 10% and 15 d) Between 15% and 20 e) More than 20% of the time

A reservation call has just been received, the probability that it will take exactly 5 minutes to receive the next reservation call is a) Between 0% and 5 b) Between 5% and 10 c) Between 10% and 15 d) Between 15% and 20%. e) More than 20%.
