1.3.7.2 Intersection of Sets

The intersection of two sets is the set containing all the elements that are common to both sets. Mathematically, the intersection of sets  and  is denoted as   . A key characteristic of the intersection is its specificity. It includes only those elements that are present in both sets. If an element is in one set but not in the other, it is not included in the intersection. Another important aspect is that each element in the intersection is unique and shared by both sets.

In set builder form, the intersection of sets  and  is represented as:

This can be interpreted as “The intersection of sets  and , denoted by , consists of all elements  such that  is an element of set  and  is an element of set .” In other words, it includes only those elements that are members of both set  and…
