Answer:
Expected Value of the return = 12.6%
Step-by-step explanation:
The expected rate of return is the weighted average of all the possible returns associated with an investment decision. The returns are weighted using the probability associated with their outcomes.
Expected return = WaRa + Wb+Rb + Wn+Rn
W- weight of the outcome, R - return of the outcome
W- Probability of the expected outcome, R- expected return under a circumstance
The probability of having a normal economy
Note that the sum of the probability of different outcomes should equal to one. Hence, the probability of economy being normal is
= 100% -(15%+30%)= 55%.
Expected Value of the return
(0.3× 30%) + (0.55× 12%) + (0.15 × -20%) =0.126
=0.126 × 100
= 12.6 %
Expected Value of the return = 12.6%
