VENN DIAGRAMS Sometimes pictures are very helpful in our thinking. First of all, a Swiss mathematician Fuler gave an idea to represent a set by the points in a closed curve. Later on, British mathematician Venn brought this idea to practice. That is why the diagrams drawn to represent sets are called Venn-Euler diagrams or simply Venn diagrams. In Venn diagrams the universal set U is represented by points within a rectangle and its subsets are represented by points in closed curves (usually circles) within the rectangle. If a set A is a subset of a set B, then the circle representing A is drawn inside the circle representing B...
