Q. Given:

\newline

Set

A=2,7,10,12

\newline

Set

B=1,4,7,8,9,12

\newline

What is the union of sets A and B?

\newline

\{1,2,4,7,8,9,10,12\}

\newline

\{7,12\}

\newline

\{2,4,7,8,10,12\}

\newline

\{1,4,8,9\}

Combine Sets $A$ and $B$ : To find the union of sets $A$ and $B$ , we combine all the elements from both sets without repeating any elements.
List Elements from Sets: List all the elements from set $A$ and set $B$ : $A = \{2, 7, 10, 12\}$ , $B = \{1, 4, 7, 8, 9, 12\}$ .
Remove Duplicates: Combine the elements and remove duplicates: $\{1, 2, 4, 7, 8, 9, 10, 12\}$ .
