Let E indicate the event that a student is taking English and C indicate the event that a student is taking chemistry.
a) Number of students taking either Chemistry or English, (E U C) = 9 + 5 + 24
= 38
b) Number of students taking Chemistry and not taking English =
C - (E 
C)
= 29 - 5
= 24
c) Number of students that are in neither Chemistry or English = 40 - (E U C)
= 40 - 38
= 2
