Probability Distributions

Question:

A discrete probability distribution that expresses the probability of a given number of events occurring over a fixed period of time or space is called a Poisson distribution if :

Options:

The events occur with a known constant mean rate

The events are dependent of the time from the occurrence of the previous event.

The rate of occurrence of events is not constant and based on time

The probability of an event is inversely proportional to the length of the period of time

Correct Answer:

The events occur with a known constant mean rate
