Stocks X and Y have the following probability distributions of expected future returns:

Probability	X	Y
0.2	-5%	-34%
0.2	4	0
0.3	11	19
0.2	20	27
0.1	34	39

Calculate the expected rate of return, rY, for Stock Y (rX = 10.50%.) Round your answer to two decimal places. %

Calculate the standard deviation of expected returns, X, for Stock X (Y = 23.88%.) Round your answer to two decimal places. %

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