"WebDec 14, 2024 · Definition 1. A Poisson process is a sequence of arrivals such that interarrival times Δti Δ t i are i.i.d with distribution Pr(Δti ≤x)= 1−e−λx Pr ( Δ t i ≤ x) = 1 − e − λ x. It just so happens, from this definition, we can show that the number of arrivals N (t) N ( t) in any interval of length t t is a Poisson random variable. " - Poisson pmf numpy
