A poll was taken of 100 students at a commuter campus to find out how they got to campus. The results are below.

37 said they drove alone.
38 rode in a carpool.
25 rode public transportation.
6 used both carpools and public transportation.
10 used both a carpool and sometimes their own cars.
6 used buses as well as their own cars.
5 used all three methods.

What is your question?

To analyze the data and answer the question, we will break it down into the different categories and calculate the number of students in each category.

1. Students who drove alone: 37 students.
2. Students who rode in a carpool: 38 students.
3. Students who rode public transportation: 25 students.
4. Students who used both carpools and public transportation: 6 students.
5. Students who used both a carpool and sometimes their own cars: 10 students.
6. Students who used buses as well as their own cars: 6 students.
7. Students who used all three methods: 5 students.

To find the number of students who used each mode of transportation exclusively, we need to subtract the students who used multiple methods from the total number of students in each category.

1. Students who drove alone exclusively: 37 - 10 (who also used a carpool) - 6 (who used buses) - 5 (who used all three methods) = 16 students.
2. Students who rode in a carpool exclusively: 38 - 10 (who also used their own cars) - 6 (who used buses) - 5 (who used all three methods) = 17 students.
3. Students who rode public transportation exclusively: 25 - 6 (who used carpools) - 6 (who used buses) - 5 (who used all three methods) = 8 students.

Therefore, the number of students who used each mode of transportation exclusively is as follows:

- 16 students drove alone
- 17 students rode in a carpool
- 8 students rode public transportation

Note: It is important to keep in mind that the total number of students who used each mode of transportation may include both students who used it exclusively and those who used it in combination with other modes.
