$\begin{array}{ccc}\text{Opinion}& \text{like}& \text{dislike}\\ \text{Number of students}& 135& 65\end{array}$

What is the probability that a student chosen at random does not like it?

(a) $\frac{13}{27}$

(b) $\frac{27}{40}$

(c) $\frac{13}{40}$

(d) $\frac{27}{13}$

Answer 1

ANSWER:
Total number of students surveyed = 200
Number of students who does not like the subject Sanskrit = 65
∴ P(Student chosen at random does not like the subject Sanskrit)
= Number of students who does not like the subject Sanskrit/Total number of students surveyed= $\frac{65}{200}$= $\frac{13}{40}$
Hence, the correct answer is option (c).
