Please do some examples where you are either given portfolio standard deviation or the portfolio expected return and you have to compute portfolio weights.

Although answer C is correct, its a little off from the actual answer. The actual answer is 0.00849, not 0.00851. The mistake is in calculating the covariance, where the actual covariance is 0.00005550, not 0.0000561. I've calculated it multiple times so I'm pretty sure of it. Hope that helps.

Same, I thought I was wrong and had to recalculate multiple times, the incorrect part was the 2nd probability 0.6(0.08-0.082)(0.05-0.04975) which should have resulted in a negative number -0.0000003, but they got it as positive 0.0000003 so ended up with covariance of 0.0000561

Thank you!

You're welcome!

5:43 in the note is a litle mistake :) The last sigma should be the rho for correlation :)

How do you determine which calculation use percentage and which arent? In example 1 the question's data use percentage, but removed in computation, but the the result is back on percentage. Thanks
