The Relationship between Exponential Distribution and Poisson Distribution

Theorem

When the time it takes for an event to occur is given by XkX_{k}, and if Xkexp(λ)X_{k} \sim \exp (\lambda), then the number of occurrences of an event per unit time is given by NN, and NPoi(λ)\displaystyle N \sim \text{Poi} (\lambda)
