1. Let's start by understanding what a Venn diagram is. 2. A Venn diagram is a visual tool used to show the relationships between different sets. 3. Each set is usually represented by a circle, and overlapping regions represent the intersection of sets. 4. For example, if we have two sets, A and B, their Venn diagram shows: - The part where only A is - The part where only B is - The part where A and B overlap (the intersection) 5. Venn diagrams help us visualize unions, intersections, and complements of sets easily and are useful in probability, logic, and statistics. If you want, I can help with specific problems involving Venn diagrams.
