Consider the following information on three stocks:

$\backslash$table$[[,,$Rate of Return If State Occurs$],[\backslash$table$[[$State of$],[$Economy$]],\backslash$table$[[$Probability of$],[$State of$],[$Economy$]],\backslash$table$[[$Stock A$],[$Stock B$]],$Stock C$,],[$Boom$,\mathrm{.}20,\mathrm{.}26,\mathrm{.}38,\mathrm{.}50],[$Normal$,\mathrm{.}50,\mathrm{.}10,\mathrm{.}08,\mathrm{.}06],[$Bust$,\mathrm{.}30,\mathrm{.}01,-\mathrm{.}20,-\mathrm{.}40]]$

a$-1.$ If your portfolio is invested $30$ percent each in A and $B$ and $40$ percent in $C,$ what is the portfolio expected return? $($Do not round intermediate calculations and enter your answer as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

a$-2.$ What is the variance? $($Do not round intermediate calculations and round your answer to $5$ decimal places, e$.$g$.,\mathrm{.}32161.)$

a$-3.$ What is the standard deviation? $($Do not round intermediate calculations and enter your answer as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

b$.$ If the expected T$-$bill rate is $3\mathrm{.}00$ percent, what is the expected risk premium on the portfolio? $($Do not round intermediate calculations abd enter your answer as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

c$-1.$ If the expected inflation rate is $2\mathrm{.}60$ percent, what are the approximate and exact expected real returns on the portfolio? $($Do not round intermediate calculations and enter your answers as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$

c$-2.$ What are the approximate and exact expected real risk premiums on the portfolio? $($Do not round intermediate calculations and enter your answers as a percent rounded to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
