Scenario Probability Rate of Return
1 0.27 −4 %
2 0.39 7 %
3 0.34 27 %

a. Calculate the expected rate of return. (Round intermediate calculations to at least 4 decimal places. Round your answer to 2 decimal places.)




b. Calculate the variance and the standard deviation of this probability distribution. (Use the percentage values for your calculations (for example 10% not 0.10). Round intermediate calculations to at least 4 decimal places. Enter your answer as a percentage rounded to 2 decimal places.)

  Variance %2  
  Standard deviation %
