The shaded portion in Figure indicates the intersection of A and B. Find the number of students who like watching at least two of the given games. Find the number of students who like watching only one of the three given games. Find the ratio of the number of students who like watching only football to those who like watching only hockey. In a survey of 500 students of a college, it was found that 49% liked watching football, 53% liked watching hockey and 62% liked watching basketball. Also, 27% liked watching football and hockey both, 29% liked watching basketball and hockey both and 28% liked watching football and basketball both.

There can be many questions formed on these kinds of sets. But you can easily solve them using little manipulation and basic addition and subtraction. With a little practice, you can easily and quickly solve questions of sets either using Venn diagrams. A universal set is the set of all possible elements that can be used in a given context. The elements within the universal set are unique and not repeated.

A Logical Reasoning & Data Interpretation contains 30% weightage in CAT exams. A Venn diagram is a diagram that reveals all attainable logical relations between a finite assortment of various units. The points inside a curve labelled S represent components of the set S, whereas points exterior the boundary characterize elements not in the set S. Scientific Research is another area in which Venn Diagrams are heavily used. A lot of scientific research is generally concerned with answering questions related to scientific phenomena, concepts, and theories.

Complement of a set denotes the elements that do not belong to the set. For example Complement of Set A is anything present in the Universe but not in Set A. The cardinality of the union of sets is the sum of the cardinalities of the individual sets, minus the cardinality of their intersection.

The two venn diagram symbols Sets X and Y are represented in a circular shape. The above Venn Diagram states that X and Y have no relation to each other, but they are part of a Universal Set. The relationship between a Set of Natural Numbers, Whole Numbers, and integers can be represented by the Venn Diagram as shown below.

How is a universal set used in set theory?

A universal set serves as a reference for identifying the elements in a particular set. It can also be used to define complements, unions, and intersections of sets. The Universal Set contains all the elements of its corresponding subsets. On the other hand, the Empty Set has no elements from its subsets. Thus, it is regarded as the complement of the Universal Set.

A Venn diagram is an illustration of the relationships between and among units, teams of objects that share something in widespread. According to the name, these types of sets have four overlapping circles or ovals. The diagram below shows the representations of the same with the various sections. In a given diagram the rectangular box indicates the universal set, and the circles indicate the related subsets. Venn diagram is a term that we have read many times in mathematics as well as reasoning topics. So what is it; these are logical diagrams used to illustrate the set relations and operations through a pictorial approach in maths.

Few Past Years Questions

Using Venn diagrams permits kids to sort data into two or three circles which overlap in the center. You indicate parts in a set by putting brackets round them. F. Edwards, Branko Grünbaum, Charles Lutwidge Dodgson (a.k.a. Lewis Carroll) developed extended implications of Venn diagrams.

complement of set

The elements that are left at last should be included in the respective Sets. Construct a Venn Diagram to denote the relationships between the following Sets i.e. We note that \(3,\,4,\,5,\,8,\,10\) are the only elements of \(U\) which do not belong to \(A\).

How does the intersection of sets relate to the universal set?

A Venn diagram consists of multiple overlapping closed curves, usually circles, every representing a set. The resulting units can then be projected back to the airplane to provide “cogwheel” diagrams with increasing numbers of tooth. These diagrams have been devised while designing a stained-glass]] window in memoriam to Venn. Venn was eager to find “symmetrical figures…elegant in themselves” representing higher numbers of units, and he devised a four set diagram using ellipses. A Venn diagram is a diagram that shows the relationship between and among a finite collection of sets.

Euler diagrams include only the actually attainable zones in a given context. In Venn diagrams, a shaded zone could characterize an empty zone, whereas in an Euler diagram the corresponding zone is missing from the diagram. For instance, if one set represents dairy merchandise and another cheeses, the Venn diagram incorporates a zone for cheeses that aren’t dairy products.

Since linguistics is a scientific study of language, it also deals with large amounts of Data, so there is a need to graphically represent that Data. A is the subSet of B, therefore, we will draw a small circle A inside the big circle B. A ∩ B implies that we have to shade the common portion of A and B. It is suggested to fill the Venn Diagram with all the possible elements that are intersecting in 2 or more 2 Sets as shown below.

Venn Diagram is an illustration made using shapes, especially circles to represent relationships, differences and similarities between two or more concepts. The usage of Venn Diagrams can be tracked in studies as early as the 1200s employed by philosopher Ramon Lull. Most of the relationships between sets can be represented by means of diagrams which are known as Venn diagrams.

This article helps students to learn in detail about Venn Diagram, symbols, operations of sets on Venn Diagram. At the end, we have discussed some solved examples which will help the child to understand this topic in a better way. In each instance above, we used a Venn diagram to characterize a given set pictorially.

Let’s have a synopsis of the uses of Set Theory and its Applications in Problems. If at all A is a finite set then the number of elements in Set A is given by n. The above diagram depicts the relationship between sets when neither A ⊂ B nor B ⊂ A. Learn about the difference of sets in various cases like A – B when neither A ⊂ B nor B ⊂ A, when A and B are disjoint Sets in the below modules.

Universal Set, and the Set of Natural Numbers is a subset of the whole Number . The universal Set is usually represented by a closed rectangle, consisting of all the Sets. The Sets and subSets are represented by using circles or ovals.

If we have two or more sets, we can use a Venn diagram to show the logical relationship among these sets as well as the cardinality of those sets. In particular, Venn Diagrams are used to demonstrate De Morgan’s Laws. Sometimes a rectangle, known as the Universal set, is drawn around the Venn diagram to characterize the house of all attainable things under consideration. There is no formula to determine the universal Set, we simply have to represent all the elements in a single Set which is collectively known as the universal Set. There is no standard symbol used to represent a universal Set. U represents the universal set that includes all the elements or objects of other Sets including its elements.

Venn diagrams enable students to organise information visually so they are able to see the relationships between two or three sets of items. Where the circles overlap shows the elements that the set have in common. A Venn diagram is a diagram that reveals all possible logical relations between a finite assortment of different sets. These diagrams depict parts as points within the aircraft, and units as regions inside closed curves.

The purpose of Venn circles is to demonstrate comparisons and contrasts between concepts with more clarity and visuals. The set of all elements or members of related sets is called a universal set and is commonly represented by the symbols E or U. For instance, in studies related to the population of humans, the universal set can be defined as the set of all individuals in the world. Meanwhile, the set of individuals in each country can be considered a subset of this universal set. A rectangle representing the universal set starts with each Venn diagram.

  • Characteristics of each set of ideas are listed in every section of the diagram, with shared characteristics listed in the overlapping sections.
  • The logical diagram mainly comprises circles within the rectangle box.
  • Learning is better done when is is interesting and engaging.
  • The Intersection of two sets \(A\) and \(B\) is the set \(C\) which consists of all those elements which are present in both \(A\) and \(B\) .
  • The orange circle, set A, represents all living creatures which are two-legged.
  • The above diagram depicts the relationship between sets when neither A ⊂ B nor B ⊂ A.

These are widely used in set theory, logical reasoning, mathematics, industries to present their assets, in the teaching sector, statistics and so on. In this heading, you will learn about the Venn diagram in sets with some most commonly used operations. These diagrams consist of rectangles and closed curves usually circles. The universal set is represented by rectangle and its subsets by circles. The overlapping region or intersection would then represent the set of all wooden tables. Shapes aside from circles can be employed as shown beneath by Venn’s personal higher set diagrams.

These diagrams depict components as factors in the aircraft, and sets as areas inside closed curves. The drawing is an example of a Venn diagram that shows the relationship among three overlapping units X, Y, and Z. The intersection relation is defined as the equal of the logic AND. The intersection of three Sets X, Y, and Z is the group of elements that are included in all the three Sets X, Y, and Z. Let us understand the Venn Diagram for 3 Sets with an example below. A Venn Diagram is a diagram that is used to represent all the possible relations of different Sets.
