State of economy	Probability State of Economy	rate of Return Stock A	rate of return Stock B	rate of return Stock C
Boom	0.64	0.1	0.18	0.36
Bust	0.36	0.1	0.04	-0.07

a.	What is the expected return on an equally weighted portfolio of these three stocks? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
b.	What is the variance of a portfolio invested 15 percent each in A and B and 70 percent in C? (Do not round intermediate calculations and round your answer to 6 decimal places, e.g., .161616.)

a.	expected return	%
b.	Variance	%
