$\Huge\color{royalblue}{ \sf 12~~C~~5= \frac{12!}{5!~\times ~(12-5)i}=\frac{12!}{5!~\times ~7i} }$ yes you got the formula right, so I am not sure what exactly did you need? perhaps you just wanted the calculator? $\large\color{blue}{ \cal combinations }$ http://www.calculatorsoup.com/calculators/discretemathematics/combinations.php $\large\color{blue}{ \cal permutations }$ http://www.calculatorsoup.com/calculators/discretemathematics/permutations.php

Fill in the details
$$
\frac{12!}{5! 7!}=\frac{8\times 9\times
   10\times 11\times12}{2\times 3\times 4\times 5}=8\times
   3\times 11\times 3=792
