Interactive practice questions

Consider the given Venn diagram.

Two overlapping circles create a Venn diagram with numbers placed in various sections. On the left, circle A contains the numbers $5$ , $4$ , and $1$ outside the overlapping area. The right circle, labeled B, contains the numbers $7$ and $14$ outside the overlapping area. The overlapping section between circles A and B contains the numbers $11$ and $6$ . The number $10$ and $12$ is placed outside both circles.
