When working with sets, as in other branches of mathematics, it is often quite useful to be able to draw a picture or diagram of the situation under consideration. A diagram of a set is called a Venn diagram. The universal set \(U\) is represented by the interior of a rectangle and the sets by disks inside the rectangle. Venn diagrams refer to the diagrammatic representation of sets using circles. The method was introduced by the English logician John Venn in 1880. It is also known as set diagrams or logic diagrams, and it is used in disciplines like mathematics, statistics, and business studies. The concept portrays an influence of set theory.

Given the following venn diagram, find n[ A ∪ ( B ∩ C ) ]. Solution: Given the Venn diagram with relevant data. From the Venn diagram, we get. n(B ∩ C) =21+3=24. and A∩B∩C = 21. In order to calculate n[ A ∪ ( B ∩ C ) ], let us use this known A ∪ B formula. n(A ∪ B)= n(A) + n(B)- n(A ∩ B) Introduction to venn diagram: notes and examples.

In the classical presentation of a three-set Venn diagram as three overlapping circles, the central region (representing elements belonging to all three sets) takes the shape of a Reuleaux triangle. The same three circles form one of the standard drawings of the Borromean rings , three mutually linked rings that cannot, however, be realized as Eg, 2, 5 and 10 are common factors of 30 and 20 in the intersection close intersection (of sets) (∩) On a Venn diagram, the region where sets overlap.
