WebBinomial Distribution Formula: The formula for the binomial distribution is: P(x) = pr(1 − p)n − r. nCr Or, P(x) = pr(1 − p)n − r. [n! / r!(n − r)!] Where, r = Total number of successful trails n = Total number of events p = Probability of … 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): A Binomial distributed random variable X ~ B(n, p) can be considered as the sum of n Bernoulli distributed random variables. So the sum of two Binomial d…
