Consider the following information about three stocks:

				Rate of Return if State Occurs
State of	Probability of
Economy	State of Economy			Stock A			Stock B			Stock C
Boom		.25			.28			.40			.52
Normal		.40			.11			.09			.07
Bust		.35			.02			.22			.42

a-1.	If your portfolio is invested 35 percent each in A and B and 30 percent in C, what is the portfolio expected return? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

a-2.	What is the variance? (Do not round intermediate calculations and round your answer to 5 decimal places, e.g., .16161.)

a-3.	What is the standard deviation? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

b.	If the expected T-bill rate is 3.10 percent, what is the expected risk premium on the portfolio? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

c-1.	If the expected inflation rate is 2.70 percent, what are the approximate and exact expected real returns on the portfolio? (Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)

c-2.	What are the approximate and exact expected real risk premiums on the portfolio?(Do not round intermediate calculations and enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)

Ps: I just need question A2 e C2. I did something wrong and I cant get the right result.
