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

Probability	A	B
0.1	(8%)	(36%)
0.2	5	0
0.3	16	24
0.3	19	28
0.1	34	37

1. Calculate the expected rate of return, r_B, for Stock B (r_A = 14.10%.) 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 = 20.69%.) 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.
