Every trial has a probability of success given by p. Since there are only two possible outcomes, this means that the probability of failure is constant (1 - p ). The r th success must occur for the x th and final trial.

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). The probability of getting exactly k successes in n independent Bernoulli trials is given by the probability mass function: … 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 Estimation of parameters When n is known, the parameter p can be estimated using the proportion of successes: See more Methods for random number generation where the marginal distribution is a binomial distribution are well-established.
