Q. Given:

\newline

Set

\mathrm{A}=2,3,4,9

\newline

Set

B=2,3,7,9,11

\newline

What is the intersection of sets A and B?

\newline

\{2,3,4,9\}

\newline

\{2,3,4,7,9,11\}

\newline

\{2,3,9\}

\newline

\{7,11\}

Find Intersection: To find the intersection, we list out the elements that are common in both sets $A$ and $B$ .
List Elements: Set A has elements $\{2, 3, 4, 9\}$ . Set B has elements $\{2, 3, 7, 9, 11\}$ .
Identify Common Elements: The common elements between sets $A$ and $B$ are $2$ , $3$ , and $9$ .
Intersection Result: So, the intersection of sets $A$ and $B$ is \{ $2$ , $3$ , $9$ \}.
