B = {y: y is the ordinate of a point on a given line}; There are infinite points on a line. For Example. . There is no natural number between 8 and 9.

Let's examine another type of set: Example 3: Let T be the set of all whole numbers. Hence, P is subset of Q. Simply, if set P is contained in set Q, P is called subset of superset Q. Here A and B are disjoint sets because these two sets don't have common element. A set is a collection of distinct objects(elements) which have common property. Here are few sample examples, given to represent the elements of a set. This means that there are no elements in the set. Example1. If a set contains only one element, then it is called a singleton set. If a set contains only one element it is called to be a singleton set. If the set is non-empty, it is called a non-empty finite set. Power Set. A = {x : x is a month in a year}; Set A will have 12 elements, B={y: y is the zero of a polynomial \((x^4~-~6x^2~+~x~+~2)\)}; Set B will have 4 zeroes. It is also called Null Set, Vacuous Set or Void Set. All the empty sets also fall into the category of finite sets. Empty set. 0 is the only whole number that is not a natural number. Read More -> Illustration. The different types of sets are as follows: Empty Set. If a set has only one element, it's known as singleton set. This set is represented by ϕ or {}. The members(elements) of set is separated by comma and braces { } are used outside the comma separated elements. Solution: T = {0, 1, 2, 3, 4, 5, 6, ...} In example 3, we used an ellipsis at the end of the list to indicate that the set goes on forever. Various types of sets: For e.g. Your email address will not be published. Example #2: What is the set of prime number? A... 2. This means that there are no elements in the set. Example #1: What is the set of all vowels in English alphabet? This set is represented by ϕ or {}. If A = {a, b, c, d} and B = {c, d}. B = {y : y is a whole number which is not a natural number}. Definition: If a set A contains elements which are all the elements of set B as well, then A is known as the subset of B. For e.g. For e.g. A = {x : x is a natural number}; There are infinite natural numbers. It is denoted by P(A). This is the set which is the base for every other set formed. Two sets are said to be equal sets if they both have exactly same elements. Empty set is denoted by ϕ. Singleton set. Equivalent sets. The concept of empty set plays a key role in the study of sets just like the role of the number zero in the study of number system. . The different types of sets are as follows: The set is empty! Required fields are marked *, Operation On Sets Intersection Of Sets And Difference Of Two Sets. A grade 5 class is a finite … A set which do not have any element is known as empty set. For example. For convenience, sets are denoted by a capital letter. Set is defined as a well-defined collection of objects. consider the set, P = {x : x is a leap year between 1904 and 1908}. Two sets are said to be overlapping sets if they have at least one element common. Hence, A is an infinite set. An empty set is hence defined as: Singleton Set. Example: If set A = {-9,13,6}, then power set of A will be: P(A)={ϕ, {-9}, {13}, {6}, {-9,13}, {13,6}, {6,-9}, {-9,13,6}}, Subsets of A= ϕ, {-9}, {13}, {6}, {-9,13}, {13,6}, {6,-9}, {-9,13,6}. Example #2: What is the set of integers between 2 and 9? Different types of sets are classified according to the number of elements they have. Definition: The power set of a set A is the set which consists of all the subsets of the set A. A set which contains limited number of elements is called a finite set. Basically, sets are the collection of distinct elements of the same type. Here, all three elements 1, 2, and 3 of set P is also member of set Q. A set with have infinite number number of elements is called infinite set. Types of Sets 1. Types of Sets Since, a Set is a well – defined collection of objects; depending on the objects and their characteristics, there are many types of Sets which are explained with suitable examples, as follows: – Empty or Null or Void Set Any Set that does not contain any element is called the empty or null or void set. A set consisting of a natural number of objects, i.e. Examples: 1 + i, 2 - 6i, -5.2i, 4. Here, A and B are equal sets because both set have same elements (order of elements doesn't matter). Empty set is denoted by ϕ. It is not possible to explicitly list out all the elements of an infinite set. Types of set. So, P = ϕ. Q = {y : y is a whole number which is not a natural number,y ≠ 0}. It is also called Null Set, Vacuous Set or Void Set. For a set A which consists of n elements, the total number of subsets that can be formed is \(2^n\). Types of Sets. Hence the set given by {1}, {0}, {a} are all consisting of ... 2. A set is called a finite set if the members of the set can be counted. The set of real numbers is a universal set of integers, rational numbers, irrational numbers.
