A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term government and corporate bond fund, and the third is a T-bill money market fund that yields a rate of 8%. The probability distribution of risky funds is as follows:

	Expected Return			Standard Deviation
Stock fund (S)		17	%		38	%
Bond fund (B)		13			18

The correlation between the fund returns is 0.12.
