🛎️ What Is a Set?
- A set is a collection of distinct objects.
- The order does not matter and there are no repeated elements.
🛎️ Understanding Venn Diagrams
- A Venn diagram is a visual representation of sets and their relationships.
- The universal set shows everything being considered.
🛎️ Intersection and Union
- The intersection (∩) means AND, so it is what is in set A and set B at the same time.
- The union (∪) means OR, so it is what is in set A or set B or both.
🛎️ Reading Numbers from a Venn Diagram
- Add all regions to find the total number in the universal set.
- Not B means elements outside set B. To find it, subtract set B from the universal set.
