The union of two sets A and B is the set that contains elements that are either in A or in B or in both A and B. The union of two sets A and B is a new set represented by A ∪ B. In the Venn diagram shown below, the yellow shaded region represents the union of sets A an...
In Venn diagrams, the universal set is usually represented by a rectangle and labeled U. Example: Draw a Venn diagram to represent the following sets: U = {1, 2, 3, 4, 5, 6, 7, 8, 9},A= {1, 2, 5, 6},B= {3, 9} ...

Venn Diagram is used to introduce additional component to the already established three subsets in the universal set. Models for intersection of only three subsets from the universal set are developed. The models are backed-up with proofs and set laws, and have actually been applied to solve ...
