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

Probability	A	B
0.1	(13%)	(40%)
0.2	6	0
0.3	13	23
0.3	22	27
0.1	36	49

1. Calculate the expected rate of return, r_B, for Stock B (r_A = 14.00%.) Do not round intermediate calculations. Round your answer to two decimal places. %

2. Calculate the standard deviation of expected returns, _A, for Stock A (_B = 22.91%.) Do not round intermediate calculations. Round your answer to two decimal places. %

3. Now calculate the coefficient of variation for Stock B. Round your answer to two decimal places.
