Answer: The answer is a
Step-by-step explanation:
Using the formula
Expected Rate of Return = ∑(i =1 to n) Ri Pi
Where Ri = Return in scenario 1
Pi = Probability for the return in scenario 1
i = Number of scenario
n = Total number of probability and Return
P1=30
R1 = 18
P2 = 50
R2 =12
P3 = 20
R3 =-5
Expected Gain =(30 ×18) + (50 × 12) + ( 20 × -5)
= 540 + 600 + - 100
= 1,040
= 1,040 ÷ 100
= 10.4%
