Consider the following information:

$\backslash$table$[[$State of Economy Probability of State of Economy,Rate of Return if State Occurs,,,$],[$Boom$,$Stock A$,$Stock B$,$Stock C$,],[$Bust$,\mathrm{.}68,\mathrm{.}11,\mathrm{.}05,\mathrm{.}26]]$

a$.$ What is the expected return on an equally weighted portfolio of these three stocks?

Note: Do not round intermediate calculations and enter your answer as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.$

b$.$ What is the variance of a portfolio invested $23$ percent each in A and $B$ and $54$ percent in C$?$

Note: Do not round intermediate calculations and round your answer to $5$ decimal places, e$.$g$.,\mathrm{.}16161.$
