Exponential Distribution

The exponential distribution, also known as the negative exponential distribution, is a probability distribution that describes time between events in a Poisson process. A Poisson process gives a way to find probabilities for random points in time for a process, and it is based on the Poisson distribution. There is a strong connection between the exponential distribution and the Poisson distribution. The Poisson distribution is a tool that helps to predict the probability of certain events occurring when you know how often the event has occurred. The exponential distribution models time between successive events over a continuous time interval, while Poisson distribution models events that happen over a fixed period of time.
