Empirical studies have suggested that the distribution of inter-arrival times is:
A) Poisson
B) Exponential
C) Uniform
D) FCFS

Question

Quizplus · Accepted Answer

The exponential distribution is used to model the time between arrivals in a Poisson process, where events occur randomly and independently at a constant average rate. This makes it a good choice for modeling the distribution of inter-arrival times in many real-world scenarios, such as arrivals at a service desk or customers entering a store. The other choices (Poisson, uniform, and FCFS) are not appropriate for modeling the distribution of inter-arrival times.
