HELP Please! I'm trying to figure out how to use the formulas below to solve this problem. Please provide extensive work and explanations I want to understand!

Background Statistical Formulas: - Expected returns: E[R]=sp(s)R(s) - Variance of returns: 2=sp(s)(R(s)E[R])2 - Standard deviation of returns: =2 - Covariance of returns: 12=sp(s)(R1(s)E[R1])(R2(s)E[R2]) - Correlation of returns: 12=12Cov(R1,R2) - Expected portfolio returns ( N assets): E[RP]=i=1NwiE[Ri] - Expected portfolio returns (2 assets): E[RP]=w1E[R1]+w2E[R2] - Portfolio variance ( N assets): P2=i=1Nj=1Nwiwjij - Portfolio variance (2 assets): P2=w1212+w2222+2w1w212
