The mean or expected value for a binomial probability distribution is ________.
A)μ = nπ(1 −π)
B)μ = π(1 −π)
C)μ = πn(1 −n)
D)μ = nπ

Question

Quizplus · Accepted Answer

The formula for the mean of a binomial probability distribution is μ = nπ, where n is the number of trials and π is the probability of success on each trial. This means that the expected value is equal to the number of trials multiplied by the probability of success.
