Overlapping sets refer to groups that share some common elements while also containing unique elements. For example, if we have two sets, A, B, C and B, C, D, the overlapping elements are B, C. This concept is often used in mathematics and statistics to analyze relationships between different categories. In everyday life, overlapping sets can be seen in various contexts, such as students who play sports and students who are in the band. The students who belong to both groups represent the overlap, illustrating how different categories can intersect and share members.
