TS EAMCET · Maths · Probability
In a college, \(40 \%\) students attend Mathematics class, \(30\% \)students attend physics class and \(20 \%\) students attend both the classes. If a student is chosen at random from the college, the probability that the student chosen attend only one class is
- A \(\frac{3}{10}\)
- B \(\frac{1}{3}\)
- C \(\frac{2}{3}\)
- D \(\frac{1}{4}\)
Answer & Solution
Correct Answer
(A) \(\frac{3}{10}\)
Step-by-step Solution
Detailed explanation
\(\because\) Students in a college \(=100 \%\) Let \(P(M)\) be the probability who attend Maths class and \(P(P)\) the probability who attend Physics classes. \( \therefore \quad P(M)=40 \%, \quad P(P)=30 \% \) \(\therefore\) Probability of students who attend only Maths…
