Chapter 13: Q. 16 (page 855)

Use the formula $C (n, r) = \frac{n!}{(n - r)! r!}$ to find the value of each combination.
$C (8, 6)$

Short Answer

Expert verified

The value of the given combination is 28.

Step by step solution

Step 1. Given information.

The given combination is $C (8, 6)$ .

Step 2. Determine the value of the given combination.

Using the formula, the given combination can be written as:

$\begin{array}{rcl} C (8, 6) & = & \frac{8!}{(8 - 6)! 6!} \\ = & \frac{8!}{2! 6!} \\ = & \frac{8 \times 7 \times 6!}{2 \times 1 \times 6!} \\ = & 28 \end{array}$

Step 3. Conclusion.

The value of the given combination is 28.
