Consider the following information:

$\backslash$table$[[$State of$,\backslash$table$[[$Probability of$],[$State of$],[$Economy$]],\backslash$table$[[$Portfolio Return$],[$If State Occurs$]]],[$Economy$,\mathrm{.}21,-\mathrm{.}17],[$Recession$,\mathrm{.}46,\mathrm{.}18],[$Normal$,\mathrm{.}33,\mathrm{.}26],[$Boom$,,]]$

Calculate the expected return. $($Do not round intermediate calculations and enter your answer as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
