Given: Set A=6,9,11 Set B=4,6,8 What is the union of sets A and B? {4,6,9,11} {4,6,8,9,11} {6} {9,11}

Identify Elements in Set A: Identify the elements in set A. Set A contains the elements 6, 9, and 11.Identify Elements in Set B: Identify the elements in set B. Set B contains the elements 4, 6, and 8.Combine Sets A and B: Combine the elements of set A and set B to find the union. The union of two sets includes all the distinct elements from both sets. Therefore, we combine all the unique elements from set A and set B without repeating any elements.List Combined Elements: List the combined elements in ascending order to represent the union. The combined elements from both sets in ascending order are 4, 6, 8, 9, and 11.Check for Repeated Elements: Check for any repeated elements and remove duplicates if any. Since the number 6 appears in both sets, we ensure it is listed only once in the union.Write Final Answer: Write down the final answer for the union of sets A and B. The union of sets A and B is {4, 6, 8, 9, 11}.

Q. Given:

\newline

Set

A=6,9,11

\newline

Set

B=4,6,8

\newline

What is the union of sets A and B?

\newline

\{4,6,9,11\}

\newline

\{4,6,8,9,11\}

\newline

\{6\}

\newline

\{9,11\}

Identify Elements in Set A: Identify the elements in set A. Set A contains the elements $6$ , $9$ , and $11$ .
Identify Elements in Set B: Identify the elements in set B. Set B contains the elements $4$ , $6$ , and $8$ .
Combine Sets $A$ and $B$ : Combine the elements of set $A$ and set $B$ to find the union. $\newline$ The union of two sets includes all the distinct elements from both sets. Therefore, we combine all the unique elements from set $A$ and set $B$ without repeating any elements.
List Combined Elements: List the combined elements in ascending order to represent the union. $\newline$ The combined elements from both sets in ascending order are $4$ , $6$ , $8$ , $9$ , and $11$ .
Check for Repeated Elements: Check for any repeated elements and remove duplicates if any. Since the number $6$ appears in both sets, we ensure it is listed only once in the union.
Write Final Answer: Write down the final answer for the union of sets $A$ and $B$ . $\newline$ The union of sets $A$ and $B$ is $\{4, 6, 8, 9, 11\}$ .
