Intersection of Sets
The shaded portion of the following Venn Diagram represents the set A ∩ B when 1) A & B are overlapping sets, 2) A & B are disjoint sets and, 3) A ⊆ B. no portion of the diagram is shaded when A & B are disjoint sets because in this case A ∩ B = φ
1) A & B are overlapping sets
In the above picture, A (Red Color) is one, and B (Green Color) is another set and the Common portion of A & B sets is marked or described by Yellow Color.
2) A & B are Disjoint Sets
3) A ⊆ B
Complement of Set –
The shaded portion of the diagram represents the set A’, which is the complement of the set.
