There is a 40% chance that an investment will earn 10%, a 40% chance that the investment will earn 12.5%, and a 20% chance that the investment will earn 30%. What is the mean expected return and the standard deviation of expected returns, respectively?
My question is how can I do it quicky with the BA II. I know how to do it for equiprobable elements but not in other cases.
Help please |
