how do I solve this problem? please show the steps so I can see where the answer came from, thanks very much

Integrative: Expected return, standard deviation, and coefficient of variation Three assets. F, G, and H-are currently under consideration by Perth Industries. The probability distributions of expected returns for these assets are shown in the follow ing table. P3-11 ab Asset F Asset G Asset H Return, r 40% 10 0 5 Return, ri 35% 10 Prl 0.10 0.20 0.40 0.20 0.10 return, 1 0.10 2 0.20 3 0.40 0.40 0.30 0.30 40% 20 10 -20 4 0.20 5 0.10 1 -20 a. Calculate the average return, F, for each of the three assets. Which provides the b. Calculate thestandard devi c. Calculate the coefficient of variation, CV, for each asset's returns. Which appears largest average return? have the greatest risk? to have the greatest relative risk? ation, or, for each asset's returns. Which appears to
