Question

Derive the mean, variance and MGF of Binomial distribution

Answer 1

Answer:

Calculation of the Mean

In order to find the mean and variance, you'll need to know both M'(0) and M''(0). Begin by calculating your derivatives, and then evaluate each of them at t = 0. ... From this, you can calculate the mean of the probability distribution. M(0) = n(pe0)[(1 – p) + pe0]n - 1 = np

Answer 2

Step-by-step explanation:
