Problem $13-9$ Returns and Variances $($LO$1,2)$

Consider the following information:

$\backslash$table$[[\backslash$table$[[$State of$],[$Economy$]],\backslash$table$[[$Probability of$],[$State of Economy$]],\frac{\text{R}\text{a}\text{t}\text{e}}{\text{S}\text{t}\text{o}\text{c}\text{k}\text{A}},$Return if State Occurs$],[],[$Boom$,0\mathrm{.}58,0\mathrm{.}07,0\mathrm{.}15,0\mathrm{.}33],[$Bust$,0\mathrm{.}42,0\mathrm{.}15,0\mathrm{.}05,-0\mathrm{.}07]]$

o$.$ What is the expected return on an equally weighted portfolio of these three stocks? $($Do not round intermediate calculations. Round the final answer to $2$ decimal places.$)$

Expected return $\%$

b$.$ What is the variance of a portfolio invested $20\%$ each in A and $B$ and $60\%$ in $C?($Do not round intermediate calculations. Round the final answer to $6$ decimal places.$)$
