Please use excel to solve and show the excel formulas so I can understand. Please include the rows and columns in your picture so I can follow along. I'll make sure to thumbs up. Thank you!

b. The partial model lists 66 different combinations of portfolio weights. For each combination of weights, find the required return and standard deviation Hint: Use the formula to calculate the variance for each portfolio and then copy it down This formula should have six values in it: 1 for Stock A, 1 for Stock B, 1 for Stock C, one for the cross-term of A and B, 1 for the cross-term of A and C, and 1 for the cross term of B and C.
