Number of elements in an empty set is zero, which is a finite number as proved above. Thus, any empty set is a finite set.

What type of set is 0?

In mathematics, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero.

What is not a finite set?

A set which is not finite is called an infinite set. Now we will discuss about the examples of finite sets and infinite sets. Then, P is a finite set and n(P) = 6.
