Quizplus · Accepted Answer

The expression $\left( \begin{array} { l } 5 \ 3 \end{array} \right)$ represents the number of ways to choose 3 items out of 5, which is calculated using the combination formula $C(n, k) = \frac{n!}{k!(n-k)!}$. Plugging in 5 for $n$ and 3 for $k$, we get $C(5, 3) = \frac{5!}{3!(5-3)!} = \frac{5 \times 4}{2 \times 1} = 10$.
