Your client chooses to invest 70% of a portfolio in your fund and 30% in a T-bill money market fund. What is the expected value and standard deviation of the rate of return on his portfolio?

The question is incomplete; You manage a risky portfolio with an expected rate of return of 18 percent and a standard deviation of 28 percent. The T-bill rate is 8 percent.

Expected value = (0.3 * 8%) + (0.7 * 18%) = 15%

Standard deviation=.7σp = 0.7 * 0.28 = 19.6%.
