To find the number of ways to arrange $n$ distinct objects, we can use the factorial way, denoted as $n!$. The formula is :
$
n!=n \times(n-1) \times(n-2) \times \cdots \times 1
$
This represents the total number of ways to arrange $n$ objects in a sequence, where each and every arrangement is different.
