If a committee of $3$ is to be chosen from a group of $38$ people of which you are a member. What is the probability that you will be on the committee
$\left( \begin{array}{l}38\\\,3\end{array} \right)$
$\left( \begin{array}{l}37\\\,2\end{array} \right)$
$\frac{{\left( \begin{array}{l}37\\{\rm{ }}2\end{array} \right)}}{{\left( \begin{array}{l}38\\{\rm{ }}3\end{array} \right)}}$.
$\frac{{666}}{{8436}}$
