Stock A:

Expected Return = 0.26 * 0.03 + 0.56 * 0.20 + 0.18 * 0.09
Expected Return = 0.1360 or 13.60%

Variance = 0.26 * (0.03 - 0.136)^2 + 0.56 * (0.20 - 0.136)^2 + 0.18 * (0.09 - 0.136)^2
Variance = 0.005596

Standard Deviation = (0.005596)^(1/2)
Standard Deviation = 0.0748 or 7.48%

Expected Return = Risk-free Rate + Beta * Market Risk Premium
0.1360 = 0.03 + Beta * 0.05
0.1060 = Beta * 0.05
Beta = 2.12

Stock B:

Expected Return = 0.26 * (-0.34) + 0.56 * 0.14 + 0.18 * 0.54
Expected Return = 0.0872 or 8.72%

Variance = 0.26 * (-0.34 - 0.0872)^2 + 0.56 * (0.14 - 0.0872)^2 + 0.18 * (0.54 - 0.0872)^2
Variance = 0.08591616

Standard Deviation = (0.08591616)^(1/2)
Standard Deviation = 0.2931 or 29.31%

Expected Return = Risk-free Rate + Beta * Market Risk Premium
0.0872 = 0.03 + Beta * 0.05
0.0572 = Beta * 0.05
Beta = 1.14

The standard deviation on Stock A's return is 7.48 percent, and the Stock A beta is 2.12. The standard deviation on Stock B's return is 29.31 percent, and the Stock B beta is 1.14. Therefore, based on the stock's systematic risk/beta, which Stock I is "riskier".
