What are permutation and combination?

A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.

Let a be the number of items selected from the group of n.

We know that the combination is given by,

ⁿCₐ = n! / [(n - a)! x a!]

The expression is given below.

⇒ 25! / [(25 - 12)! x 12!]

Then the expression can be written as,

⇒ ²⁵C₁₂

Then the expression 25! / [(25 - 12)! x 12!] represents the combination.
