In a survery, students were asked whether they play basketball or tennis. Of 34 students, 24 play basketball and 13 students play tennis.4 students play neither. How many students play both sports?
Is it 7 students?

Correct!
Of 34 students, 4 play neither, so there are 30 students who play at least one sport.
24 and 13 make 37, so 3730=7 students play both.
