There are two risky assets and one risk-free asset available for investment. The two risky assets have the following features: Asset X has an expected return of 25% and a variance of returns of 625%2 (0.04). Asset Y has an expected return on 20% and a standard deviation of returns of 20%. The covariance between the returns on X and Y is 500%2 (0.0500). Short selling risky assets is NOT allowed. The risk-free asset offers a return of 8%. a) Plot the expected returns and standard deviations of returns of the three assets in a graph. Draw the set of feasible portfolios of only the RISKY assets onto the same graph. Please note: no need to very accurate in your drawing of the assets or the feasible set.

C). What level of standard deviation risk does an investor have to hold in order to achieve an expected return of 18% on their portfolio?
