B)binomial distribution
C)normal distribution
D)negative exponential distribution

Question

Quizplus · Accepted Answer

The interarrival time in waiting line problems is the time between arrivals of customers. It is assumed to follow the negative exponential distribution because it models the behavior of rare independent events such as the arrival of customers. The Poisson distribution is related to the number of arrivals in a given time interval, not the interarrival time. The binomial distribution models the number of successes in a fixed number of independent trials, which is not relevant to waiting line problems. The normal distribution can be used to model the distribution of some variables but is not appropriate for modeling the interarrival time in waiting line problems.
