Consider the following information on a portfolio of three stocks:

State of Economy	Probability of State of Economy	Stock A Rate of Return	Stock B Rate of Return	Stock C Rate of Return
Boom	.14	.05	.35	.47
Normal	.52	.13	.25	.23

Required:
(a)	If your portfolio is invested 42 percent each in A and B and 16 percent in C, what is the portfolios expected return, the variance, and the standard deviation? (Do not round intermediate calculations. Round your variance answer to 5 decimal places (e.g., 32.16161) and input your other answers as a percentage rounded to 2 decimal places (e.g., 32.16).)

Expected return	%
Variance
Standard deviation	%

(b)	If the expected T-bill rate is 4.4 percent, what is the expected risk premium on the portfolio? (Do not round intermediate calculations. Enter your answer as a percentage rounded to 2 decimal places (e.g., 32.16).)
