Find the Number of Possibilities five choose two

${}_{5}C_{2}$

Evaluate ${}_{5}C_{2}$ using the formula ${}_{n}C_{r} = \frac{n!}{r! (n - r)!}$ .

$\frac{5!}{2! (5 - 2)!}$

Subtract $2$ from $5$ .

$\frac{5!}{2! (3)!}$

Clarify $\frac{5!}{2! (3)!}$ .

Tap for more steps...

Should be rewritten $5!$ as $5 \cdot 4 \cdot 3!$ .

$\frac{5 \cdot 4 \cdot 3!}{2! (3)!}$

The common factor should be canceled of $3!$ .

Tap for more steps...

Cancel the common factor.

$\frac{5 \cdot 4 \cdot 3!}{2! (3)!}$

Reformulate the expression.

$\frac{5 \cdot 4}{2!}$

First, multiply $5$ by $4$ .

$\frac{20}{2!}$

Clarify the denominator.

Tap for more steps...

Expand $2!$ to $2 \cdot 1$ .

$\frac{20}{2 \cdot 1}$

Initially, multiply $2$ by $1$ .

$\frac{20}{2}$

First, divide $20$ by $2$ .
