In a school, 33% of the students study Biology and 16% study Chemistry. If 9% study both sciences, what percentage do not study either subject?

Answer 1

DRAW VENN disgarm
say there are 100
33 - 9 = 24 study only Bio
16 - 9 = 7 study only chemistry
that is a total of 24 + 9 + 7= 40 that study at least one of them
so
100 - 40 = 60% play hockey instead
