Stocks A and B have the following probability distributions of expected future returns:

Probability A B

0.1 (6%) (38%)

0.2 2 0

0.3 16 22

0.3 24 30

0.1 34 46

Calculate the expected rate of return, rB, for Stock B (rA = 15.20%.) Do not round intermediate calculations. Round your answer to two decimal places. % Calculate the standard deviation of expected returns, A, for Stock A (B = 22.41%.) Do not round intermediate calculations. Round your answer to two decimal places. % Now calculate the coefficient of variation for Stock B. Round your answer to two decimal places.
