Let's look at the following example to understand the process of finding the union of sets. We have two sets A and B as A = {a, b, j, k} and B = {h, t, k, c}. We need to find out the elements present in the union of A and B. As per the definition of the union of two sets, the resultant set will include elements that are present in A, in B or both s...
We use a unique mathematical notation to represent each set operation. The mathematical notation that is used to represent the union between two setsis '∪'. This operator is called infix notation and it is surrounded by the operands. Consider two sets P and Q, where P = {2,5,7,8} and Q = {1,4,5,7,9}. P ∪ Q = {1,2,4,5,7,8,9}. Venn Diagrams refer to ...
As per the commutative property of the union, the order of the operating sets will not affect the resultant set. This means that if the position of the operands is changed, the solution will stay the same and it will not be affected. In mathematical terms, we can say that:A ∪ B = B ∪ A Let's consider two sets P and Q: P = {a, m, h, k, j}, Q = {2, 3...
As per the associative property of union, when the sets are grouped using parentheses, the result will not be affected. This means that when the parentheses’ position is changed in any expression of sets that involves union, then the resultant set will not be affected by this. In mathematical terms, (A ∪ B) ∪ C = A ∪ (B ∪ C), where A, B, and C are ...
The idempotent property states that the union of any set with the same set will result in the set itself. It can be shown mathematically as A ∪ A = A. Let's prove this for A = {2,4,6,8,10} Thus, A ∪ A = {2,4,6,8,10} ∪ {2,4,6,8,10} = {2,4,6,8,10} = A
As per the property of a null set, the union of any set with a null set or an empty set will result in the set itself. Mathematically, we can write it asA ∪ Ⲫ = A. Let's prove this for A = {p,q,r} Thus, A∪∅ = {p,q,r} ∪ {} = {p,q,r}
As per the property of the universal set, the union of the universal set with any set results in the universal set. Mathematically it can be represented as A ∪ U = U. Let's prove this for A = {a,e} and U = {a,b,c,d,e,f,g,h} then A∪U = {a,e} ∪ {a,b,c,d,e,f,g,h} = {a,b,c,d,e,f,g,h} = U Related Articles on Union of Sets Check out the following pages r...
Jul 10, 2024 · The formula for the union of two sets (A union B ) is given in set builder notation as: A ∪ B = {x | x ∈ A or x ∈ B} This means x is an element of A ∪ B if and only if x is an element of A or x is an element of B. Union of Sets and Venn Diagram. In the Venn diagram, the shaded region illustrates the union of sets A and B.
Oct 10, 2024 · The representation of similar types of data is called the set. Union of a set is the basic operation on the sets which is used to find all the entries of the given sets. It is one of the operators on the set used to solve the set theory problems. Union of two sets means finding a set containing all the values in both sets.
The set notation is generally written using symbols between the sets for set operations, and certain symbols for representing some special kind of sets. The set notation for the union of sets is A U B, for the intersection of sets is A ∩ B. And the set notation for representing some important sets is the μ - universal set, Ø - null set.
11. The Union of Sets. The union of set A and set B is the set that contains all elements in set A or set B or in both set A and set B. We denote A and B’s union by A ⋃ B and read it as ‘A union B.’ We can also use the set-builder notation to define the union of A and B, as shown below.

The union of the set is denoted by the symbol ‘∪’. In the given Venn diagram, the red-coloured portion represents the union of both sets A and B. Thus, the union of two sets A and B is given by a set C, which is also a subset of the universal set U such that C consists of all those elements or members which are either in set A or set B or ...
