<div>Prof. Gehr,</div>

<div>Can you please help me with figuring out how to do problem #8 on the sample midterm? I don't know where I am going wrong. If we have the weights, standard deviations, and the correlation between the 2 securities, I would think finding the stan dev. of the portfolio would be easily calculated. However, I must be missing a step or multiple steps. Can you please advise me on this problem please? Thanks.</div>
