Answer 2

To solve the problem using a Venn diagram, we need to represent the information given and find the number of students who fall into each category. Let's break down the information step by step:

Given information: - Total number of students in sports sections: 38 - Number of students in the football section: 24 - Number of students in the volleyball section: 33

To find the number of students who: d) Only attend the volleyball section b) Do not attend the football section c) Do not attend the volleyball section

Representing the information in a Venn diagram:

Let's start by drawing a rectangle to represent the total number of students in sports sections. Inside this rectangle, we will draw two overlapping circles to represent the football and volleyball sections.

       |                 |
       |_________________|

   /                         \
  /                           \
 /                             \
Volleyball Section

Filling in the numbers:

We know that the total number of students in sports sections is 38. So, we write this number outside the rectangle.

       |_________________|

 /                             \
Volleyball Section

Total: 38

Next, we fill in the number of students in the football section, which is 24. We write this number inside the football circle.

          Football Section

       |                 |
       |                 |
       |_________________|
      /                   \

  /                           \
 /                             \
Volleyball Section

Total: 38

Similarly, we fill in the number of students in the volleyball section, which is 33. We write this number inside the volleyball circle.

Volleyball Section
       |        33       |

Total: 38

Solving the problem:

Now, let's find the number of students who fall into each category:

d) Only attend the volleyball section: To find this number, we need to subtract the number of students who attend both the football and volleyball sections from the total number of students in the volleyball section. From the diagram, we can see that the overlapping region represents the students who attend both sections. Since we don't have this information, we can't determine the exact number of students who only attend the volleyball section.

b) Do not attend the football section: To find this number, we need to subtract the number of students in the football section from the total number of students. So, the number of students who do not attend the football section is 38 - 24 = 14.

c) Do not attend the volleyball section: To find this number, we need to subtract the number of students in the volleyball section from the total number of students. So, the number of students who do not attend the volleyball section is 38 - 33 = 5.

Please note that without the information about the overlapping region, we cannot determine the exact number of students who only attend the volleyball section (d).

I hope this helps! Let me know if you have any further questions.
