What is the complement of a ∩ B?
A Intersection B Complement is equal to the union of the complements of the sets A and B. Mathematically, it is written as (A ∩ B)' = A' U B'. It is one of the important De-Morgan's Law of sets.
What is a complement diagram?
In the mathematical field of graph theory, the complement or inverse of a graph G is a graph H on the same vertices such that two distinct vertices of H are adjacent if and only if they are not adjacent in G.
What is complement in math example?
The complement of set A is defined as a set that contains the elements present in the universal set but not in set A. For example, Set U = {2,4,6,8,10,12} and set A = {4,6,8}, then the complement of set A, A′ = {2,10,12}.
What is the complement of 7?
Decimal example The nines' complement of a decimal digit is the number that must be added to it to produce 9; the nines' complement of 3 is 6, the nines' complement of 7 is 2, and so on, see table.
What does a ∩ B mean?
The intersection operation is denoted by the symbol ∩. The set A ∩ B—read “A intersection B” or “the intersection of A and B”—is defined as the set composed of all elements that belong to both A and B.
What is AnB )' in Venn diagram?
Intersection The intersection of two sets A and B, written AnB, is the overlap of the two sets.
What is the complement of Set C?
The complement is notated A', or Ac, or sometimes ~A. A universal set is a set that contains all the elements we are interested in. This would have to be defined by the context. A complement is relative to the universal set, so Ac contains all the elements in the universal set that are not in A.
How do you find the complement of a graph?
The complement of a graph G is a graph G' on the same set of vertices as of G such that there will be an edge between two vertices (v, e) in G', if and only if there is no edge in between (v, e) in G. Complement of graph G(v, e) is denoted by G'(v, e').

What is the complement of a complete graph?
The complement of the complete graph Kn is the graph on n vertices having no edges (an independent set of n vertices).
How do you find the complement in a sentence?
In grammar, it's a word or group of words that completes a grammatical construction: A complement is part of the predicate of a sentence and describes either the subject of the sentence or the direct object. If it modifies the subject, it is called a subject complement.
What is the complement of the function f '= X Y Z '+ YZ?
This is an Expert-Verified Answer The complement will be f' = (x' + y)(x'*(y+z'))(y).
How do you find the complement of a Boolean equation?
The complement of Boolean function is f' = p′q+pq′'. Step 1 − Use DeMorgan's theorem, x+y' = x'. y'.
What is the complement of XYZ?
Explanation: The complement is obtained by converting the complement terms to normal terms and vice versa. Also, the OR and AND operators are interchanged. Here, X'Y'Z gets converted to X+Y+Z'.
Sets Definition
A well-defined collection of objects or elements is known as a set. Any set consisting of all the objects or elements related to a particular context is defined as a universal set.
Complement of a Set Definition
If [latex]U [/latex] is a universal set and [latex]A [/latex] be any subset of [latex]U [/latex] then the complement of [latex]A [/latex] is the set of all members of the universal set [latex]U [/latex] which are not the elements of [latex] A [/latex].
Complement of a Set Examples
To make it more clear consider a universal set [latex]U [/latex] of all natural numbers less than or equal to 20.
What is a Venn diagram?
Venn diagrams are the diagrams that are used to represent the sets, the relation between the sets, and the operation performed on them in a pictorial way. Introduced by John Venn (1834-1883), the concept uses circles (overlapping, intersecting, and non intersecting) to denote the relationship between sets. It is also known as a set diagram or a logic diagram.
Why is Venn's diagram useful?
Venn’s diagrams are particularly helpful in solving word problems on number operations that involve counting. Once it is drawn for a given problem, the rest should be a piece of cake.
What is the universal set in Venn diagram?
For drawing a Venn diagram first, the universal set should be known. Every set is a subset of the universal set, meaning that every other set will be inside the rectangle. It represents the universal set. All the elements of the set should be inside the circle. Also, they are part of a bigger rectangle, making them the elements of the universal set.
How is class 12 CBSE marked?
CBSE class 12 exam will be marked by considering the marks of mid-term, unit tests or pre-board.
What is the complement of set A?
A' is the complement of set A. This set has all the elements that are absent in set A.
How to find union B?
A Union B is given by: A ∪ B = {x | x ∈A or x ∈B}.
What is A-B in math?
A-B is read as A difference B. Sometimes, it is referred to as a relative complement. It represents elements of set A which are not there in set B.
Steps for Shading a Venn Diagram to Indicate the Complement of an Event
Step 1: Identify the portion of the Venn Diagram representing the event in question.
What is a Venn Diagram and a Complement?
Venn Diagram: A Venn diagram is a picture consisting of overlapping shapes, most commonly circles, in which each shape represents an event. Venn diagrams can be used to better visualize unions, intersections, and complements of events.
Examples Shading a Venn Diagram to Indicate the Complement of an Event
The Venn diagram below shows the results of a survey asking 200 families if they own a dog or a cat. Shade the complement of the event of owning a cat.
Venn Diagrams Symbols
- Union (∪): Represents the union of all sets – i.e., the universe of all elements within X and Y sets. Intersection (∩): Represents all elements shared or common within the selected sets or groupings. Intersection represents shared elements (in the middle) within sets X and Y. Complement (XC): Represents whatever is not represented in a particular s...
History of Venn Diagrams
- The Venn diagram concept was established by British mathematician and logician John Venn. It was first published in his 1980 journal titled “On the Diagrammatic and Mechanical Representation of Propositions and Reasonings.” However, the development of Venn diagrams can be traced back to the 1200s through philosopher and logician Ramon Llull, who drew simila…
Using Venn Diagrams
- As highlighted above, Venn diagrams are used in several ways to show relationships between various set elements. Below are examples of uses of Venn diagrams.
Cylinder Venn Diagrams
- Venn diagrams do not just show overlaps but can also show subsets within a larger set or group. We illustrate below the British Islands, which clearly shows the subsets of each island from the larger set of British Islands.
Creating A Venn Diagram
- A Venn diagram can be created in several ways. Below are various tools used to construct Venn diagrams: 1. By using Shapes in Microsoft Office (Word, Excel, PowerPoint) 2. By using SmartArt in Microsoft Office (Word, Excel, PowerPoint) 3. By using online drawing tools such as canva, SmartDraw, visual-paradigm, visme, and creately, among others.
Benefits of Venn Diagrams
