Venn Diagrams help visualize relationships between sets, making it easier to understand and solve problems involving unions, intersections, and differences.

Front

If 6 students own only dogs and 3 own only cats, how many students own pets?

Back

If there are no overlaps, then 6 (dogs) + 3 (cats) = 9 students own pets.

Front
