The current one$-$year Treasury bill rate is $4\mathrm{.}74$ percent and the expected one$-$year rate $12$ months from now is $5\mathrm{.}20$ percent. According to the unbiased expectations theory, what should be the current rate for a two$-$year Treasury security?

Note: Do not round intermediate calculations. Round your percentage answer to $2$ decimal places $($e$.$g$.,32\mathrm{.}16).$
