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		.22			.30			.42			.58
Normal		.46			.23			.21			.19
Bust		.32			.01			.22			.50

a-1	If your portfolio is invested 25 percent each in A and B and 50 percent in C, what is the portfolio expected return? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

Portfolio expected return

10.09 %

a-2	What is the variance? (Do not round intermediate calculations and round your answer to 5 decimal places, e.g., 32.16161.)

Variance = .087

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

Standard deviation

29.5 %

b.	If the expected T-bill rate is 4.30 percent, what is the expected risk premium on the portfolio? (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)

Expected risk premium

5.79 %

c1	If the expected inflation rate is 3.90 percent, what are the approximate and exact expected real returns on the portfolio? (Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)

Approximate expected real return	________ %
Exact expected real return	________ %

c2	What are the approximate and exact expected real risk premiums on the portfolio? (Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.)

Approximate expected real risk premium	________ %
Exact expected real risk premium	________ %

This is the entire problem. I have answered everything besides c1 and c2. Those are the only 2 parts I need solved.
