Binomial DistributionThe mean of the distribution (μx) is equal to n * P .The variance (σ2x) is n * P * ( 1 - P ).The standard deviation (σx) is sqrt[ n * P * ( 1 - P ) ].

Variance of the binomial distribution is a measure of the dispersion of the probabilities with respect to the mean value. The variance of the binomial distribution is σ2=npq, where n is the number of trials, p is the probability of success, and q i the probability of failure.
Since the events are not correlated, we can use random variables' addition properties to calculate the mean (expected value) of the binomial distribution μ = np . The variance of a binomial distribution is given as: σ² = np(1-p) . The larger the variance, the greater the fluctuation of a random variable from its mean.Apr 6, 2022
The first variable in the binomial formula, n, stands for the number of times the experiment runs. The second variable, p, represents the probability of one specific outcome.

While the p variance is a function for calculating the variance, we are not sure how it is related to p value. The p value is used to either accept or reject a hypothesis. Usually, the null hypothesis is rejected if the p value is less than 0.05.Mar 3, 2021
The Binomial Distribution Each trial results in one of the two outcomes, called success and failure. The probability of success, denoted p, remains the same from trial to trial. The n trials are independent. That is, the outcome of any trial does not affect the outcome of the others.

Binomial probability refers to the probability of exactly x successes on n repeated trials in an experiment which has two possible outcomes (commonly called a binomial experiment). If the probability of success on an individual trial is p , then the binomial probability is nCx⋅px⋅(1−p)n−x .
