Binomial Distribution

What does Binomial Distribution mean in American Law?

The definition of Binomial Distribution in the law of the United States, as defined by the lexicographer Arthur Leff in his legal dictionary is:

In statistics, the theoretically expected distribution of a series of random samples drawn from a population divided into two categories, e.g., male/female. It will give, e.g., the number of samplings that, if randomly made, would come up 100% male, 90% male, 80% male, etc., against which one can measure the actual result of actual samplings, thus to discover if the result in the actual case indicates the presence of a significant variable or is just as likely to be the result of randomness.
