The Binomial distribution is a discrete probability distribution that models the number of successes in a fixed number of independent Bernoulli trials (experiments with two possible outcomes, often termed "success" and "failure"). This type of distribution is particularly useful in situations where you want to determine the likelihood of a certain number of successes within a series of trials.
