Answer:
A)6 B)2 C)1
Explanation:
For A: There are 6 students because 5 are originally in the Spanish club, while 1 is in both clubs. This still means David is in the Spanish club so there are 6 students.
For B: There are 2 students because the condition is that, only students in the Math club are counted. In this scenario, David doesn't count because he is part of both clubs. So only Isabel and Carmen count, which means there are only 2 people.
For C: There is 1 student because the condition is that, only the students in both clubs count. The place where the two circles overlap will hold the student who is in both clubs. In that area, there is only David, making it so there is one 1 student.
