Countability refers to the concept in mathematics and logic that deals with the number of elements or objects that can be put into a one-to-one correspondence with the natural numbers. In other words, it is the ability to count or enumerate the elements of a set.<br><br>Countability is often used to distinguish between two types of sets:<br><br>1. Countable sets: These are sets that can be put into a one-to-one correspondence with the natural numbers, meaning that their elements can be counted and listed. Examples of countable sets include the set of integers, the set of rational numbers, and the set of pairs of natural numbers.<br>2.
