The problem in the image asks for two things based on the results of a survey about the employment of 40 villagers, with the information that people can have more than one job. The data breakdown is as follows:

- 24 people work as farmers
- 24 people work as entrepreneurs
- 28 people work as civil servants (PNS)
- 5 people work as both farmers and entrepreneurs
- 8 people work as both civil servants and entrepreneurs
- 7 people work as both farmers and civil servants
- 10 people work in all three categories: farmers, entrepreneurs, and civil servants

The two tasks are:
1. **Create a Venn diagram** based on the given data.
2. **Determine the number of people** who only have one type of job (either farmer, entrepreneur, or civil servant). Also, check if there are any people without a job, and if so, provide the number.

### To solve these tasks:
1. We need to use the principle of inclusion and exclusion to correctly allocate the individuals in the Venn diagram (for the three categories).
2. From that, we will calculate how many people are involved in only one occupation by considering the overlaps.

Shall I proceed to create the Venn diagram and solve the second task mathematically?

A survey was conducted on 40 villagers to determine their occupations. The data shows that each person can have more than one job. The breakdown is as follows:
- 24 people work as farmers
- 24 people work as entrepreneurs
- 28 people work as civil servants (PNS)
- 5 people work as both farmers and entrepreneurs
- 8 people work as both civil servants and entrepreneurs
- 7 people work as both farmers and civil servants
- 10 people work in all three categories: farmers, entrepreneurs, and civil servants

Tasks:
1. Create a Venn diagram based on the given data.
2. Determine how many people have only one job (either farmer, entrepreneur, or civil servant). Check if there are any people without a job, and if so, how many.
