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

Probability	A		B
0.1	(13	%)	(25	%)
0.2	6		0
0.5	15		22
0.1	22		29
0.1	37		40

1. Calculate the expected rate of return, , for Stock B ( = 13.30%.) 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 = 17.65%.) 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.
