# Question: We have seen that for a binomial distribution with n

We have seen that, for a binomial distribution with n trials, each with probability of success P, the mean is as follows:

μX = E[X] = nP

Verify this result for the data of Example 4.7 by calculating the mean directly from

μX = ΣxP(x)

showing that for the binomial distribution, the two formulas produce the same answer.

μX = E[X] = nP

Verify this result for the data of Example 4.7 by calculating the mean directly from

μX = ΣxP(x)

showing that for the binomial distribution, the two formulas produce the same answer.
