6 C 6

${}_{6}C_{6}$

Step 1

Evaluate

6 C 6

${}_{6}C_{6}$ using the formula

n C r = \frac{n!}{(n - r)! r!}

${}_{n}C_{r} = \frac{n!}{(n - r)! r!}$ .

\frac{6!}{(6 - 6)! 6!}

$\frac{6!}{(6 - 6)! 6!}$

Step 2

Subtract

6

$6$ from

6

$6$ .

\frac{6!}{(0)! 6!}

$\frac{6!}{(0)! 6!}$

Step 3

Simplify

\frac{6!}{(0)! 6!}

$\frac{6!}{(0)! 6!}$ .

Step 3.1.1

Cancel the common factor.

$\frac{6!}{(0)! 6!}$

Step 3.1.2

Rewrite the expression.

$\frac{1}{(0)!}$

$\frac{1}{(0)!}$

Step 3.2

Expand

$(0)!$ to

$1$ .

$\frac{1}{1}$

Step 3.3

Divide

$1$ by

$1$ .
