WebFeb 17, 2024 · Binomial Probability Distribution Formula. It is defined as the probability that occurred when the event consists of “n” repeated trials and the outcome of each trial may or may not occur. The formula for binomial probability is as stated below: p (r out of n) = n!/r! (n − r)! × p r (1 − p) n – r = n C r × p r (1 − p) n−r. WebThe probability mass function of a binomial random variable X is: f ( x) = ( n x) p x ( 1 − p) n − x. We denote the binomial distribution as b ( n, p). That is, we say: X ∼ b ( n, p) where the tilde ( ∼) is read "as distributed as," and n and p are called parameters of the distribution.
