Formula for Cardinality of Sets?

In case, two or more sets are combined using operations on sets, we can find the cardinality using the formulas given below. Formula 1 : n(A u B) = n(A) + n(B) - n(A n B)

How do you find the cardinality of a set?

Consider a set A. If A has only a finite number of elements, its cardinality is simply the number of elements in A. For example, if A={2,4,6,8,10}, then |A|=5.

What is cardinality of the given set?

In mathematics, the cardinality of a set is a measure of the "number of elements" of the set. For example, the set contains 3 elements, and therefore. has a cardinality of 3.
