I have completed this problem but wondered if someone would check it for me. Thanks, Victoria

a. What is the expected return of a stock given the following information:

State of Probability Return
Economy

Good .2 20%
Normal .5 12
Poor .3 5

(0.20)(.20)+(.50)(.12)+(.30)(.05) =11.5%

b. What is the standard deviation of returns?

(.2)(.20-0.115)^2 + (.5)(.12-0.115)^2 + (.3)(.5-0.115)^2 =

0.0014450 + 0.0000125 + 0.0444675 = sqrt (0.0459250) =

0.21430 or 21.43%
