Also, relating to or derived from the binomial theorem or the binomial distribution; binomial coefficient: a coefficient of a term in a binomial expansion; binomial distribution: a frequency distribution of the possible number of successful outcomes in a given number of trials in each of which there is the same probability of success; binomial equation: an equation reducible to the form xn − A = 0; binomial expansion: an expansion of a power of a binomial; binomial series: an infinite series obtained by expanding (x + y)n, where n is not a positive integer or zero; also, a binomial expansion; binomial theorem: the general algebraic formula, discovered by Newton, by which any power of a binomial quantity may be found without performing the progressive multiplications.
