# Venn Diagram Applet

How many Venn diagrams can be formed using two sets within a universe S? Are they all exhibited below?

## Description

In this applet, ` A` and ` B` are subsets of a universal set `S`. The list above gives the 16 different subsets of `S` that can be constructed from ` A` and ` B`
using the basic set operations of union ($\cup$), intersection ($\cap$), and complement ($^c$). The
selected subset is colored red in the Venn diagram on the right.
