Definitions:

Poisson Distribution

A probability distribution that expresses the probability of a given number of events occurring in a fixed interval of time or space if these events occur with a known constant rate and independently of the time since the last event.

Probability Of Occurrence

The likelihood that a specific event will happen, often expressed as a number between 0 and 1.

Span Of Time

Span of time refers to the duration or length of a period between two points in time.

Poisson Distribution

A probability distribution that expresses the probability of a given number of events happening in a fixed interval of time or space, assuming these events happen with a known constant rate and independently of the time since the last event.
