The binomial distribution is the basis for the popular binomial test of statistical significance. 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. If the sampling is carried out without replacement, the draws are … 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 … 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; its distribution is Z=X+Y ~ B(n+m, p): 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 … See more Probability mass function In general, if the random variable X follows the binomial distribution with parameters n ∈ $${\displaystyle \mathbb {N} }$$ and p ∈ [0,1], we write X ~ B(n, p).
