Consider the following information:

			Rate of Return if State Occurs
State of	Probability of
Economy	State of Economy			Stock A			Stock B			Stock C
Boom		.15			.33			.43			.23
Good		.55			.18			.14			.12
Poor		.25			.05			.08			.06
Bust		.05			.13			.18			.10

a.	Your portfolio is invested 26 percent each in A and C, and 48 percent in B. What is the expected return of the portfolio? (Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
b-1.	What is the variance of this portfolio? (Do not round intermediate calculations and round your answer to 5 decimal places, e.g., .16161.)
b-2.	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.)

Please note that the answers of b1 and b2 were incorrect as the screenshot showed above. Please give the correct answers of a, b1 and b2 questions, and the reason about why my answers of b1 and b2 were wrong. Thank you.
