Apollo Ltd has the following estimated probability distribution of returns: RETURN Probability 4 % 0
Apollo Ltd has the following estimated probability distribution of returns:
| RETURN | Probability |
| 4 % | 0.2 |
| 12 % | 0.5 |
| 14% | 0.3 |
Calculate Apollo Ltd’s expected return, the variance and standard deviation of its expected return and the return’s coefficient of variation
Expert Solution
Expected return = Probability*Return
= .2*4% + .5*12% + .3*14% = .8% + 6% + 4.2% = 11%
Expected return = 11%
Variance = .2*(.04-.11)^2 + .5*(.12-.11)^2 + .3(.14-.11)^2 = .0013
Variance = .0013
Standard deviations = √.0013 = 3.61%
Standard deviations = 3.61%
Coefficient of variation = Standard deviations/Return
= 3.61%/11% = .33
Coefficient of variation = .33
