law of large numbers

[′lȯ əv ¦lärj ′nəm·bərz]
(statistics)
The law that if, in a collection of independent identical experiments, N (B) represents the number of occurrences of an event B in n trials, and p is the probability that B occurs at any given trial, then for large enough n it is unlikely that N (B)/ n differs from p by very much. Also known as Bernoulli theorem.
