Answer:

For a Poisson Distribution

The standard deviation is always equal to the square root of the mean: . The exact probability that a Poisson random variable X with mean μ is equal to a is given by the formula. P X = a = μ a a !

Notation: Poisson(λ)

Mean: λ

Distribution: k=1,2,…

Parameter: λ>0
