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

Probability	A	B
0.2	(10%)	(21%)
0.2	3	0
0.3	13	23
0.2	24	30
0.1	28	38

a.Calculate the expected rate of return, rB, for Stock B (rA = 10.10%.) Do not round intermediate calculations. Round your answer to two decimal places.

b.Calculate the standard deviation of expected returns, A, for Stock A (B = 20.37%.) Do not round intermediate calculations. Round your answer to two decimal places.

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