Venn Diagrams

We need some way to discuss sets without listing all the elements in order to show certain relationships between the sets. Venn diagrams have one or more circle/s that represent set/s inside a rectangle representing the universal set.

In section 6.1 in the text, Figure 1 shows a universal set containing two sets: A, and B. The overlapping of sets A and B indicates the possibility that some elements are common to both of these sets. These common elements would be found in the overlap area.
