WebTranscribed Image Text: In 1898, L. J. Bortkiewicz published a book entitled The Law of Small Numbers. He used data collected over 20 years to show that the number of soldiers killed by horse kicks each year in each corps in the Prussian cavalry followed a Poisson distribution with a mean of 0.61. Web12 The Poisson distribution has become known as the law of small numbers or of rare events. These are misnomers which proved detrimental to the realization of the fundamental role of the Poisson distribution. The following examples will show how misleading the two names are.

This gives the probability of x successes in n trials when p is too small for the more general formula.

Theorem 3.1 (weak version). Let P be a distribution on N0 with mean λ. Then T1/n (P∗n) converges pointwise to Po(λ) for n → ∞. Proof. First we note that T1/n (P∗n) = T1/n (P) ∗n.
