I need assistance finding the variance and deviation!

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		.16		.363	.463	.343
Good		.44		.133	.113	.183
Poor		.34		.023	.033	.075
Bust		.06		.123	.263	.103

Requirement 1: Your portfolio is invested 29 percent each in A and C and 42 percent in B.

What is the expected return of the portfolio? (Do not round intermediate calculations. Enter your answer as a percentage rounded to 2 decimal places (e.g., 32.16).)

Expected return of the portfolio 11.41 %

Requirement 2: (a) What is the variance of this portfolio? (Do not round intermediate calculations. Round your answer to 5 decimal places (e.g., 32.16161).)

Variance of the portfolio (b)

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

Standard deviation %
