It's ok tha t the probability is = 90
please make sure the answer is correct 100%
1) Expected rate of return on C
Economic Status | Rate of return | Probablity | Expected return |
Optimistic | 12% | 0.30 | 3.60 |
Most Likely | 9% | 0.50 | 4.50 |
Pessimistic | -8% | 0.10 | -0.80 |
Total | 7.30% |
2) Variance and Standard Deviation
Economic Status | Rate of return | Probablity | (Return - average)2 |
Probablity * (Return - average)2 |
Optimistic | 12% | 0.30 | 22.09 | 6.627 |
Most Likely | 9% | 0.50 | 2.89 | 1.445 |
Pessimistic | -8% | 0.10 | 234.09 | 23.409 |
Total | 31.481 |
Variance = [ Sum of Probablity * (Return - average)2 ]
= 31.481 %2
Standard Deviation = [ Sum of Probablity * (Return - average)2 ]1/2
= [ 31.481 ]1/2
= 5.61% Answer
3) Sharpe ratio = [ ( Expected retun on security - Risk free rate ) / Standard deviation ]
= [ ( 7.3 - 4 ) / 5.61 ]
= 0.5882 Answer
