A Union B Formula. The union of two sets A and B is a set that contains all the elements of A and B and is denoted by A U B (which can be read as "A or B" (or) "A union B"). A union B formula is used to find the union of two sets A and B. The union can be found by just putting all the elements of A and B in one set and removing duplicates. i.e.,

The union of any two or more sets is a set that contains all the elements of the previous sets. The union of two setsis equivalent to the logical operation OR and it means any of the given values, for example, if we take a set A = {a, e, i, o, u} and set B = {a, b, c, d, e} then OR operations signifies any of the value of set A and set B and this c...
We can easily find the union of two sets by taking all the elements of both sets and removing the common elements. Let’s learn this concept through an example. Example: Find the union of the sets, set A = {p, q, r, s, t, u} and set B = {s, t, u, v, w,}. Solution:
Union of the sets is represented using the symbol “∪”. It is placed between two sets whose union is to be found. We read this symbol as “union”. Example A∪B is read as A union B, furthermore we can also find the union of two or more sets as the union of set A, set B, and set C is represented as, A∪B∪C and is read as A union B union C. Note:We can f...
As we already discussed set A union B contains all the elements of set A as well as set B, but there are some formulas related to the A U B operation that helps us calculate many things. One such formula involving union of two sets, is discussed as follows:
To find the number of elements in the set of A union B, we can use the following formula: Also Check: Intersection of Sets
The union of the set can also be represented using the Venn Diagrams. For example, if we have set A and set B which have some values in common then their Venn diagram is represented in the image below, We can represent any set using the Venn diagram in the Venn diagram explained above the rectangle represents the Universal set, and set A and set B ...
The intersection of sethas various properties. The table below discusses the properties of the union of the set. Now let’s learn about these properties in detail.
Example 1: Find the Union of the sets, 1. A = {1, 2, 3, 4, 5, 6} 2. B = {5, 6, 7, 8, 9} Solution: Example 2: Find the Union of the sets given below, 1. P = {a, e, i, o, u} 2. Q = {p, q, r, s, t} 3. R = {j, k, l, m, n} Solution: Example 3: Find the union of sets P and Q, if P = {1, 2, 3, 4, 5} and Q = Ⲫ. Solution: Example 4: Find the union of Q = Se...
Problem 1: Let set A={1,2,3,4,5} and setB={4,5,6,7,8}. Find A ∪B. Problem 2: Given set C={a,b,c} and set D={c,d,e}, calculate C ∪D. Problem 3: If set E={2,4,6,8,10} and set F={3,6,9,12}, determine E∪F. Problem 4: Consider two sets: set G={x,y,z} and set H={w,x,y}. Find G ∪H.
The union is used to gather all the distinct elements from the sets being considered, providing a comprehensive collection of elements without any repetition. This concept is essential for students in Class 11 as it lays the groundwork for more advanced topics in mathematics. Understanding the union of sets helps students in comprehending how to co...
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.
The set operation, that is the union of sets, is represented as: A ∪ B = {x: x ∈ A or x ∈ B}. Here, x is the element present in both sets, A and B. Finding a Union of Sets. 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 rely on them to prove or derive new results. The intersection of two sets A and B, denoted A ∩ B, is the set of elements common to both A and B. In symbols, ∀x ∈ U [x ∈ A ∩ B ⇔ (x ∈ A ∧ x ∈ B)]. The union of two sets A and B, denoted A ∪ B, is the set that combines all the elements in A and B.

A Venn diagram is also called a set diagram or a logic diagram showing different set operations such as the intersection of sets, union of sets and difference of sets. It is also used to depict subsets of a set. For example, a set of natural numbers is a subset of whole numbers, which is a subset of integers.
