a)
Probability of state 1=p1=0.2
Return in state 1=r1=-10%
Probability of state 2=p2=0.7
Return in state 2=r2=8%
Probability of state 3=p3=0.1
Return in state 3=r3=20%
Expected Return=p1*r1+p2*r2+p3*r3=0.2*(-10%)+0.7*8%+0.1*20%=5.60%
b)
Probability of state 1=p1=0.3
Return in state 1=r1=3%
Probability of state 2=p2=0.5
Return in state 2=r2=5.8%
Probability of state 3=p3=0.2
Return in state 3=r3=9%
Expected Return=p1*r1+p2*r2+p3*r3=0.3*3%+0.5*5.8%+0.2*9%=5.60%
c)
Expected return is same i.e. 5.6% in both cases. So, decision cannot be made solely on the basis of expected return.
As, expected return is same in both cases, Ali should calculate the measure of risk i.e. standard deviation of both proposals and should select the proposal with lower risk i.e. lower standard deviation.
