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

Probability	A	B
0.1	(14%)	(31%)
0.2	6	0
0.3	10	18
0.2	19	26
0.2	34	49

Calculate the expected rate of return, r_B, for Stock B (r_A = 13.40%.) Do not round intermediate calculations. Round your answer to two decimal places. %

Calculate the standard deviation of expected returns, _A, for Stock A (_B = 22.57%.) 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.
