Answer #1

Probability Portfolio Returns
0.25 =0.45*0.30+0.45*0.42+0.10*0.54=0.378
0.45 =0.45*0.12+0.45*0.10+0.10*0.08=0.107
0.30 =0.45*0.03-0.45*0.24-0.10*0.44=-0.1385

1.
Expected returns=0.25*(0.378)+0.45*(0.107)+0.30*(-0.1385)=0.1011

2.
Variance=0.25*(0.378-0.1011)^2+0.45*(0.107-0.1011)^2+0.30*(-0.1385-0.1011)^2=0.036406515

3.
Standard Deviation=sqrt(0.036406515)=0.190804913

4.
Expected risk premium=0.1011-0.032=0.0691
