Using Euler-Venn Diagrams to Analyze Equipment Possession Among Students

To answer the questions about the number of students possessing different types of equipment, we can use Euler-Venn diagrams. These diagrams are useful for visualizing the relationships between different sets of items.

Number of Students with Different Equipment: - Barbell: 8 students - Badminton: 10 students - Dumbbells: 6 students

Now, let's use this information to answer the specific questions using Euler-Venn diagrams.

Number of Students with Different Equipment According to Euler-Venn Diagrams

1. Students with Barbell: - According to the Euler-Venn diagram, 8 students have a barbell.

2. Students with Badminton: - The Euler-Venn diagram shows that 10 students have badminton.

3. Students with Dumbbells: - As per the Euler-Venn diagram, 6 students possess dumbbells.

4. Students with Barbell and Badminton: - The intersection of the circles representing barbell and badminton shows that 5 students have both barbell and badminton.

5. Students with Barbell and Dumbbells: - The intersection of the circles representing barbell and dumbbells indicates that 3 students have both barbell and dumbbells.

6. Students with Badminton and Dumbbells: - The intersection of the circles representing badminton and dumbbells reveals that 4 students have both badminton and dumbbells.

7. Students with Barbell, Badminton, and Dumbbells: - The region where all three circles intersect shows that 2 students have all three types of equipment.

By analyzing the Euler-Venn diagrams, we can determine the number of students possessing different types of equipment and the intersections between these sets.
