Stocks A and B have the following probability distributions of expected future returns: Probability A B 0.1 (5 %) (38 %) 0.2 2 0 0.4 16 24 0.2 18 27 0.1 31 50 Calculate the expected rate of return, , for Stock B ( = 13.00%.) Do not round intermediate calculations. Round your answer to two decimal places. % Calculate the standard deviation of expected returns, A, for Stock A (B = 22.54%.) Do not round intermediate calculations. Round your answer to two decimal places. % Now calculate the coefficient of variation for Stock B. Do not round intermediate calculations. Round your answer to two decimal places
