Question

what is union of sets​

Answer 1

Answer:

the union of sets is simply known as combining of two sets in ascending order.

Step-by-step explanation:

example:

A={1,5,9,11}

B={4,7,5,9}

union of sets

AuB ={1,5,9,11} u {4,7,5,9}

A uB={1,4,5,7,9,11}

Answer 2

Union Of Sets:

• Let A and B be two sets

• The Union of A and B is the set of all elements of A and all elements of B.

• The Symbol we used to denote union of sets is 'U'.

• Example of a union set in set builder form.

• A U B = {x:x ∈ A or x ∈ B}

• Ex: A = {1, 2, 3, 4}   B = {3, 4, 5, 6}

• A U B = {1, 2, 3, 4, 5, 6}

• Attached below is the Venn Diagram showing us the union of sets.

• From the Venn diagram we understand that the intersection contains elements of both A and B.
