Answer 2

Answer:

$\frac{8!}{6!2!}=28$

Step-by-step explanation:

we know that factorial of any natural number can be calculated as

n! = n . n-1. n-2...n-(n-1)

So  

here to calculate $\frac{n!}{m! r!}$

where n=8,r=2,m=6

$\frac{8!}{6!2!}\\\\\\=\frac{8.7.6.5.4.3.2.1}{6.5.4.3.2.1.2.,} \\\\\\=\frac{8.7}{2}\\\\\\=28$
