If arrivals follow a Poisson probability distribution, the time between successive arrivals must follow a(n) _____ probability distribution.

A) Poisson
B) normal
C) uniform
D) exponential

Exponential Distribution

A probability distribution used to model the time between events in a Poisson process, describing the times between events in a continuous but rare occurrence.

Poisson Probability

The probability of a given number of events happening in a fixed interval of time or space if these events occur with a known constant mean rate and independently of the time since the last event.

Successive Arrivals

The sequence in which entities arrive one after another, often analyzed in queue theory and time-series analysis.
