Given: Set A=1,2,5,6,9,10 Set B=3,6,7,8,11 What is the union of sets A and B? {1,2,3,5,6,7,8,9,10,11} {6} {1,2,5,9,10} {1,6,7,9,10,11}

Identify Elements of Set A: Identify the elements of set A. Set A = {1, 2, 5, 6, 9, 10}Identify Elements of Set B: Identify the elements of set B. Set B = {3, 6, 7, 8, 11}Combine Unique Elements: Combine all unique elements from sets A and B to form the union. The union of sets A and B, denoted as A ∪ B, includes every element that is in A, in B, or in both A and B without repeating any elements.List Combined Elements: List the combined elements in ascending order without repetition. A ∪ B = {1, 2, 3, 5, 6, 7, 8, 9, 10, 11}Check for Missing Elements: Check for any missing or repeated elements in the union. All elements from both sets are present, and there are no repetitions.

Q. Given:

\newline

Set

A=1,2,5,6,9,10

\newline

Set

B=3,6,7,8,11

\newline

What is the union of sets A and B?

\newline

\{1,2,3,5,6,7,8,9,10,11\}

\newline

\{6\}

\newline

\{1,2,5,9,10\}

\newline

\{1,6,7,9,10,11\}

Identify Elements of Set A: Identify the elements of set A. $\newline$ Set $A = \{1, 2, 5, 6, 9, 10\}$
Identify Elements of Set B: Identify the elements of set $B$ . $B = \{3, 6, 7, 8, 11\}$
Combine Unique Elements: Combine all unique elements from sets $A$ and $B$ to form the union. $\newline$ The union of sets $A$ and $B$ , denoted as $A \cup B$ , includes every element that is in $A$ , in $B$ , or in both $A$ and $B$ without repeating any elements.
List Combined Elements: List the combined elements in ascending order without repetition. $\newline$ $A \cup B = \{1, 2, 3, 5, 6, 7, 8, 9, 10, 11\}$
Check for Missing Elements: Check for any missing or repeated elements in the union. All elements from both sets are present, and there are no repetitions.
