# Statistics - Exponential Distribution

exponential distribution is the probability distribution of the time between events in a Poisson process.

The value (mostly time) between each pair of consecutive events in a Poisson process has an exponential distribution

## Example

### Waiting time

waiting time follows an Exponential Distribution in the real world Exponential distributions follow the “waiting time” between events such as visits to a web site within a fixed interval.

### Arrival process

Exponentially distributed random numbers are typically used to model arrival processes in simulation models.
