Stocks A and B have the following probability distributions of
expected future returns: PROBABILITY: 0.1, 0.2, 0.4, 0.2, 0.1 Stock
A: 8%, 5,13, 21,29 Stock B. 36%, 0, 22, 25, 36. Calculate the
expected rate of return, rB, for Stock B (rA = 12.50%.) Do not
round intermediate calculations. Round your answer to two decimal
places. Calculate the standard deviation of expected returns, ?A,
for Stock A (?B = 19.68%.) Do not round intermediate calculations.
Round your answer to two...
