The number of two of the nine members of ski patrol unit can be chosen is equal to the combinations of 9 taken 2. This can be calculated using the formula:

$\frac{9!}{2!*(9-2)!}$

= $\frac{9!}{2!*7!}$ , where

9! =9×8×7×6×5×4×3×2×1 and

7!=7×6×5×4×3×2×1

2!=2×1 then the equation becomes:

= $\frac{9*8}{2}$ =36
