- A8
- B11

- D9
Solution & Step-by-step Explanation
To find the number of female teachers who are NOT married:We need to look for the region common to both Females (represented by the Triangle) and Teachers (represented by the Circle).Since they must NOT be married, we exclude the region covered by the Married category (represented by the Rectangle).The number in the intersection of the Triangle and Circle that lies outside the Rectangle is .Therefore, the number of unmarried female teachers is 9.
