When success is not an impossible event, then the mean of Binomial distribution is

Options

  1. Aalways more than its variance
  2. Balways equal to its variance
  3. Calways less than its variance
  4. Dalways equal to its standard deviation

Correct answer

A. always more than its variance

Step-by-step solution

When success is not an impossible event, then p 0, q 0 . Mean =n p and variance =n p q aligned & p, q p q & n p>n p q aligned Mean > Variance Mean is greater than variance.
