Answer:
8.34%
Explanation:
expected return of the stock = ∑(likeliness to occur of every economic state x expected return) = (1/3 x 20%) + (1/3 x 15%) - (1/3 x 10%) = 6.67% + 5% - 3.33% = 8.34%
The value of the expected return is equal to the sum of the individual returns times the percentage of likeliness to occur.
