How many 5-card hands make full house

Hi

I have the feeling I am wrong somewhere, I try to calculate the number of 5-card hands that make full house.

$13\cdot \binom{4}{3}\cdot 12 \cdot \binom{4}{2}$

thanks

. . $\begin{array}{cc}\text{Number of values for the Triple:} & 13 \\<br /> \text{Number of ways to get the Triple:} & {4\choose3} \\ <br /> \text{Number of values for the Pair:} & 12 \\<br /> \text{Number of ways to get the Pair:} & {4\choose2} \end{array}$

Absolutely correct!
