Answer

The cardinality of a set is the number of elements in the set. So, we just need to count the number of elements in the set AB.

Steps

Step 1 :The intersection of these two sets would be the set of elements that are common to both sets, which is AB={2,4}.

Step 2 :The cardinality of a set is the number of elements in the set. So, we just need to count the number of elements in the set AB.
