The expression $\left( \begin{array} { l } 9 \ 5 \end{array} \right)$ represents a combination, which calculates the number of ways to choose 5 items out of 9 without regard to order. It is calculated as $\frac{9!}{5!(9-5)!} = \frac{9!}{5!4!} = \frac{9 \times 8 \times 7 \times 6}{4 \times 3 \times 2 \times 1} = 126$.
