She also found out that the risk (standard deviation) of each stock is 25% and that the five stocks are independent from one another. After examining this information, the portfolio manager created an equal-weighted portfolio of stocks C, D, and E.

b. What is the best portfolio one can create out of five stocks? Calculate the expected return and the standard deviation of the best portfolio.
