Can you please show numbers inserted in formulas? Need to show full work with formulas presented. Thanks!
I see that part, I guess I was just wondering how you achieved the variance of the third security because it was not given. And the covariance.
ok, what about the part of the formula that states (Cov s1,s2) (Cov s3,s2) (Cov s1, s3) and then I get it :-)
Right but what are they?How do you find them?
So variance and covariance are the same? I am sorry, I didn't know they were the same.
