Portfolio expected return and standard deviation

Consider the following predicted returns for two stocks:

Economy	Probability of State of the Economy	Return on Stock A	Return on Stock B
Severe recession	.10	(.30)	(.15)
Mild recession	.20	(.25)	(.10)
Normal growth	.50	.20	.20
Boom	.20	.40	.20

If you invest 40% of your money in Stock A and 60% in Stock B:

a. What will your portfolios return be in each state of the economy? (Rounding: Do not round intermediate calculations. Enter your final answers as decimals with four decimal places, e.g., if your answer is 9.5%, you would enter .0950.)

Severe recession:

Mild recession:

Normal growth:

Boom:

b. What will your portfolios expected return be? (Rounding: Do not round intermediate calculations. Enter your final answer as a decimal with four decimal places, e.g., if your answer is 9.5%, you would enter .0950.)

c. What will your portfolios standard deviation be? (Rounding: Do not round intermediate calculations. Enter your final answer as a decimal with four decimal places, e.g., if your answer is 9.5%, you would enter .0950.)
