A random variable X that takes on one of the values 0,1,2,... is said to be a Poisson random variable with parameter λ if, for some λ>0,

p(i)=P{X=i}=e^-λλⁱ/i! i=0,1,2,... (7.1)

Equation (7.1) defines a probability mass function, since

∑p(i)=e^-λ∑λⁱ/i!=e^-λe^λ=1

The Poisson probability distribution was introduced by Siméon Denis Poisson in a book he wrote regarding the application of probability theory to lawsuits, criminal trials, and the like. This book, published in 1837, was tentitled Recherches sur la probabilité des jugements en matière criminelle et en matière civile (Investigations into the Probability of Verdicts in Criminal and Civil Matters).
