Definitions:

Poisson Probability Distribution

A discrete frequency distribution which gives the probability of a number of independent events occurring in a fixed period of time or space if these events happen with a known constant mean rate and independently of the time since the last event.

Continuous Probability Distribution

A function that describes the likelihood of any outcome within a continuous range of outcomes occurring.

Poisson Distribution

A statistical distribution describing the probability of a given number of events happening in a fixed interval of time or space, assuming events occur with a constant mean rate and independently of the time since the last event.

Mean

The average of a set of numbers, calculated by dividing the sum of all the numbers by the count of numbers.
