The expected value is the: a. inverse of the standard deviation b. correlation between a security’s risk and return. c. weighted average of all possible outcomes. d. same as the discrete probability distribution. (c) 2. Given the following probability distribution, calculate the expected return of security XYZ. Security XYZ's Potential return Probability 20% 0.3 30% 0.2 -40% 0.1 50% 0.1 10% 0.3 a. 16 percent Solution: b. 22 percent E(R) = Σ R i pr i c. 25 percent = (20)(0.3) + (30)(0.2) + (- 40)(0.1) + (50)(0.1) + d. 18 percent = (10)(0.3) = 22 percent (b) 3.
