When n is large, the binomial distribution with parameters n and p can be approximated by the normal distribution with mean np and variance np1 p provided that p is not too large or too small. 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 yesno question, and each with its own booleanvalued outcome.

If a random variable x follows the binomial distribution with parameters n and p, we write. Casio fx9750gii binomial formula distribution, including. The binomial distribution is used to model the total number of successes in a fixed number of independent trials that have the same probability of success, such as modeling the probability of a given number of heads in ten flips of a fair coin.

Alternatively, one or more arguments can be scalars. This calculator will compute the cumulative distribution function cdf for the binomial distribution, given the number of successes, the number of trials, and the probability of a successful outcome occurring. Geary has shown, assuming that the mean and variance are finite, that the normal distribution is the only distribution where the mean and variance calculated from a set of independent draws are independent of each other.
