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

mX = E3X4 = nP Verify this result for the random variable “number of heads” in an experiment tossing three coins by calculating the mean directly from mX = axP1x2 showing that for the binomial distribution, the two formulas produce the same answer.
