Question:

We have seen that, for a binomial 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 the two formulas produce the same answer. Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
