Question

Find mean and variance of a Binomial distribution with parameter n and p

Answer 1

Answer:

The probability distribution of a binomial random variable is called a binomial distribution. ... The 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 ) ].
