TS EAMCET 6-Aug-2021 Shift 1 Question Paper

∵ Students in a college =100%
Let P(M) be the probability who attend Maths class and P(P) the probability who attend Physics classes.∴‌‌P(M)=40%,‌‌P(P)=30%
∴ Probability of students who attend only Maths
class =P(M)−P(M∩P)
=40%−20%=20%
Probability of students who attend only Physics
class =P(P)−P(M∩P)
=30%−20%=10%
∴ Probability that the student chosen attend only
one class =20%+10%=30%
‌‌P=30∕100=3∕10
