    combination formula number of choices = nCr = n!/(r!*(n-r)!) where n = total number of people (13) and r = the number of people on the team = 10

    \[\left(\begin{matrix}6+7 \\ 10\end{matrix}\right)=\left(\begin{matrix}13 \\ 10\end{matrix}\right)=\\\left(\begin{matrix}13 \\ 3\end{matrix}\right)=\frac{13*12*11}{3.2.1}=13*2*11\]
