Let's solve the Venn diagram problem step by step.
Understanding the Venn Diagram:
The diagram has three overlapping circles representing:
-
Math Club
-
Arts Club
-
Music Club
Each section shows the number of students in specific combinations of clubs.
Here’s how we interpret the numbers:
-
Only Math Club: 22
-
Only Arts Club: 15
-
Only Music Club: 7
-
Math and Arts (but not Music): 8
-
Math and Music (but not Arts): 6
-
Arts and Music (but not Math): 5
-
All three clubs (Math, Arts, Music): 12
-
None of the clubs: 18
---
Now, answer each question:
####
1. How many students joined only the math club?
This is the part of the Math circle that does
not overlap with any other club.
→
22
✔ Answer: 22
---
####
2. How many students joined the arts club?
This includes
all students in the Arts Club circle:
- Only Arts: 15
- Arts and Math (not Music): 8
- Arts and Music (not Math): 5
- All three: 12
Add them up:
15 + 8 + 5 + 12 =
40
✔ Answer: 40

####
3. How many students joined a club but did not join the math or arts clubs?
This means they joined
only the music club, since it's the only club left.
→ Only Music Club:
7
✔ Answer: 7
---
####
4. How many students joined both the arts club and the music club?
This includes:
- Arts and Music, but not Math: 5
- All three clubs: 12
So total = 5 + 12 =
17
✔ Answer: 17
---
####
5. How many students did not join any clubs?
This is the number outside all circles:
→
18
✔ Answer: 18
---
####
6. How many students joined all the three clubs?
This is the center where all three circles overlap:
→
12
✔ Answer: 12
---
✔ Final Answers:
1.
22
2.
40
3.
7
4.
