I need C and D, already have A and B. Please show how to do it on Excel with formulas and how to use the solver. and show how to make the chart.

6. The following table contains the probability distribution for the returns of three securities over the next year. Expected Returns Scenario Probability 1 II TII T-bills #1 0.03 -17% 5% 33% 3% #2 0.07 -9% 11% 17% 3% #3 0.15 7% 17% 7% 3% #4 0.50 14% 25% 1% 3% #5 0.15 19% 29% .9% 3% #6 0.07 27% 34% -17% 3% #7 0.03 35% 44% -27% 3% a) Determine the expected return and standard deviation of each security. b) Calculate a variance and covariance matrix for these four securities using the given probabilities. c) Calculate a set of five portfolios that make up the capital market line using the Solver. d) Create a chart of the CML including the original securities
