Answer 1

Answer:

The correct option is c.

Step-by-step explanation:

The given expression is

$^{12}C_{8}$

Combination formula:

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

Using the formula we get

$^{12}C_{8}=\frac{12!}{8!(12-8)!}$

$^{12}C_{8}=\frac{12\times 11\times 10\times 9\times 8!}{8!(4)!}$

$^{12}C_{8}=\frac{12\times 11\times 10\times 9}{4\times 3\times 2\times 1}$

$^{12}C_{8}=495$

Therefore the correct option is c.
