The equation for the variance of the binomial distribution is given by: A)p^x (1 - p)^n-x B)np C)np (1-p)

Question

Quizplus · Accepted Answer

The equation for the variance of the binomial distribution is np(1-p), where n is the number of trials and p is the probability of success on each trial. Option A appears to be an incorrect formula. Option B is only the expected value or mean of the distribution. Option D is not a valid choice as it is not one of the given options. Therefore, option C is the best choice as it correctly represents the formula for variance of the binomial distribution.
