Sally Rogers has decided to invest her wealth equally across the following three assets

what are her expected returns and the risk from her investment and three assets?

how do they compare with investing in asset M alone?

could sally reduce her total risk even more by using M and N only, assets M and O only or assets N and O only? use 50/50 split between the asset pairs, and fund the standard deviation of each asset pair

what is the expected return of investing equal in all three assets M,N and O
