The Poisson Distribution

Modelling with the Poisson DistributionSign up

understand the conditions under which a random variable can be modelled by Po(λ): events occurring independently at a constant average rate λ in a fixed interval · be able to calculate Poisson probabilities, use E(X) = Var(X) = λ, and use the Poisson distribution as an approximation to the binomial when n is large and p is small
