• Union (A∪B) combines all elements.
• The union of two sets includes every element found in Set A, Set B, or in both sets. There are no repeated elements in the final set.
• Intersection (A∩B) finds common elements.
• The intersection contains only the elements that appear in both Set A and Set B. If an element is not shared, it is not included.
• Disjoint sets have no common elements.
• Two sets are called disjoint when they have no elements in common. Their Venn diagram shows two separate circles with no overlapping region, and A∩B=∅ (the empty set).
