Hey!

In maths, a countable set refers to a set which has the same number of elements as that of a subset of a set of natural numbers..
It can a finite set or an infinite set..

A set S is said to be countable, if there is an injective function f from S to the natural numbers N = { 1, 2, 3 ........}

Hope it helps^^
