Question

7. Liqin fixes up old cars and sells them to supplement his retirement income. Liqin came across a beat-up 1955 Corvette that she is considering rebuilding and selling. She estimates a 0.2 probability that she will gain 15% on the deal, a 0.2 probability that she will gain 10%, and a 0.6 probability that she will gain 5%. Liqin's expected return for fixing up and selling the Corvette is ____%. a. 8 b. 11 c. 20 d. 30

Answer 1

a. 8%

Step-by-step explanation:

Expected Return = [(Return*Probability)+(Return*Probability)+(Return*Probability) * 100%]

Expected Return = [{(15%*0.2)+(10%*0.2)+(5%*0.6)} * 100]%

Expected Return = [{(0.15*0.2)+(0.1*0.2)+(0.05*0.6)} * 100]%

Expected Return = [{0.03+0.02+0.03} * 100]%

Expected Return = [{0.08 * 100}]%

Expected Return = 8%

So, Liqin's expected return for fixing up and selling the Corvette is 8%.
