You put $30\%$ of your money in T$-$bills and $70\%$ in the risky portfolio P$.$

$$ Assume expected return and standard deviation of the risky portfolio P

equal $15\%$ and $22\%.$ In notation, E$($rP$)=0\mathrm{.}15$ and $\backslash$sigma P $=0\mathrm{.}22.$ Also

assume that the risk$-$free return rf $=0\mathrm{.}07.$

$$ What$$s the expected return and standard deviation of this complete

portfolio C$?$
