Please help with this problem. I am so lost on what to do.

Problem 13-18 Optimal Sharpe Portfolio Value-at-Risk (LO3, CFA6) You are constructing a portfolio of two assets, Asset A and Asset B. The expected returns of the assets are 10 percent and 16 percent, respectively. The standard deviations of the assets are 27 percent and 35 percent, respectively. The correlation between the two assets is .37 and the risk-free rate is 5.4 percent. What is the optimal Sharpe ratio in a portfolio of the two assets? What is the smallest expected loss for this portfolio over the coming year with a probability of 1 percent? (A negative value should be indicated by a minus sign. Do not round intermediate calculations. Round your Sharpe ratio answer to 4 decimal places and the z-score value to 3 decimal places when calculating your answer. Enter your smallest expected loss as a percent rounded to 2 decimal places.)
