Formulas for Binomial Distribution's PMF, CDF, Expected Value, and Variance: In a Binomial Experiment, there are Bernoulli Trials. These trials are independent and each trial has a success probability of and a failure probability of . The random variable that count the total number of successes is the Binomial and it follows the Binomial Distribution is denoted by .

Expert Answer





The probability mass function (PMF) of the binomial distribution is given by:

P(X = x) = (nCx) * p^x * (1 - p)^(n - x)



Let's justify this formula step by step:

1. (nCx) represents the number of ways to choose x successes out of n trials, which is calcul...
