Photo by Erik Mclean from Pexels ctc speedtestThe binomial distribution is the basis for the popular binomial test of statistical significance. [1] The binomial distribution is frequently used to model the number of successes in a sample of size n drawn with replacement from a population of size N. See more In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a See more Expected value and variance If X ~ B(n, p), that is, X is a binomially distributed random variable, n being the total number of experiments and p the probability of each experiment yielding a successful result, then the expected value of X is: See more Sums of binomials If X ~ B(n, p) and Y ~ B(m, p) are independent binomial variables with the same probability p, then X + Y is again a binomial variable; … See more This distribution was derived by Jacob Bernoulli. He considered the case where p = r/(r + s) where p is the probability of success and r and s are positive integers. Blaise Pascal had earlier considered the case where p = 1/2.
