(i) Individuals exposed to chemical C1 but not to chemical C2 =
Individual exposed to chemical C1 - Individual exposed to both chemicals C1 and C2
= 120-30 = 90
(ii) Individual exposed to chemical C2 but not to chemical C1 =
individual exposed to chemical C2 - Individuals exposed to chemicals C1 and C2
=50-30 = 20
(iii) Individuals exposed to chemicals C1 or C2 = Individual exposed to C1 + Individual exposed to chemical C2 - Individuals exposed to both C1 and C2
=120+50-30 = 140
