Venn diagrams are the pictorial representation of elements that use circles or any other shapes to show the relationship between given elements. Circles that overlap have a commonality while circles that do not overlap do not share those aspects. Venn diagrams help to visually represent the similarities and variations between two concepts. Venn diagrams also named Set diagrams or Logic diagrams, are widely used in mathematics, statistics, logic, teaching, linguistics, computer science, and business to show the data in pictorial form. We are going to discuss here Venn diagrams examples with questions in detail.
Venn Diagrams Reasoning
Venn diagram is an important topic in the general intelligence or reasoning section which is asked in almost all the exams. The Venn diagram in reasoning is used to represent the data or concept through diagrams or pictures. We are going to discuss the Venn Diagrams Questions and Examples in this article. So refer to this article to get all the details of Venn diagrams and their related concepts.
Types of Venn Diagrams
Generally, Venn diagrams are of three types namely two-element Venn diagram, three-element Venn diagram, and four elements Venn diagram depending on the given condition. You can understand all the types through the Venn diagrams questions given in the article.
Venn Diagrams Symbols
Venn diagrams symbols are used to represent the relationship between given elements. The Venn diagrams symbols with examples are discussed below.
- Union (∪): It represents the union of all the sets – i.e., the universe of all elements within X and Y sets. The union of the set is given here.
- Intersection (∩): Intersection represents all elements shared or common within the selected sets or groups. It represents the shared or common elements (in the middle) within the sets X and Y.
- Complement (XC): Complement represents whatever is not represented in a particular set; in this case, everything not in set X. An equation to illustrate the complement of X is XC = U/A, where U illustrates a given universe of elements. The diagram below shows the absolute complement of X in U.
Venn Diagrams Formulas
Venn diagrams formulas are used to solve the problems based on Venn diagrams easily. The Venn diagrams formulas for 2 and 3 sets are discussed here.
- n ( A ∪ B) = n(A ) + n ( B ) – n ( A∩ B)
- n (A ∪ B ∪ C) = n(A ) + n ( B ) + n (C) – n ( A ∩ B) – n ( B ∩ C) – n ( C ∩ A) + n (A ∩ B ∩ C)
- And so on, where n(A) = number of elements in set A.
Venn Diagrams for Sets
A set is a collection of things or elements shown by the pictures. Venn diagrams for sets are given here with examples. Refer to these questions to understand the topic in detail.
