Chapter 12: Q. 210E (page 1213)

In the following exercises, evaluate.
(a) $(\begin{array}{l} 8 \\ 1 \end{array})$ (b) $(\begin{array}{l} 10 \\ 10 \end{array})$ (c) $(\begin{array}{l} 6 \\ 0 \end{array})$ (d) $(\begin{array}{l} 9 \\ 3 \end{array})$

Short Answer

Expert verified

(a) $8$

(b) $1$

(d) $84$

Step by step solution

Part (a) Step 1 Given information

Evaluate $(\begin{array}{l} 8 \\ 1 \end{array})$

Part (a) Step 2 Solution

$\begin{array}{rcl} (\begin{array}{l} 8 \\ 1 \end{array}) & = & \frac{8!}{(8 - 1)! \cdot 1!} \\ = & 8 \end{array}$

Part (b) Step 1 Given information

Evaluate $(\begin{array}{l} 10 \\ 10 \end{array})$

Part (b) Step 2 Solution

$\begin{array}{rcl} (\begin{array}{l} 10 \\ 10 \end{array}) & = & \frac{10!}{(10 - 10)! \cdot 10!} \\ = & 1 \end{array}$

Part (c) Step 1 Given information

Evaluate $(\begin{array}{l} 6 \\ 0 \end{array})$

Part (c) Step 2 Solution

$\begin{array}{rcl} (\begin{array}{l} 6 \\ 0 \end{array}) & = & \frac{6!}{(6 - 0)! \cdot 0!} \\ = & 1 \end{array}$

Part (d) Step 1 Given information

Evaluate $(\begin{array}{l} 9 \\ 3 \end{array})$

Part (d) Step 2 Solution

$\begin{array}{rcl} (\begin{array}{l} 9 \\ 3 \end{array}) & = & \frac{9!}{(9 - 3)! \cdot 3!} \\ = & 84 \end{array}$
