Question

Out of 200 students from a school, 135 like Kabbaddi and the remaining students do not like the game. If one student is selected at random from all the students, find the probability that the student selected dosen't like Kabbaddi.

Answer 1

Total number of students = 200
Number of students who like Kabbaddi = 135
Therefore, number of students who don't like Kabbaddi = 200 − 135
= 65
Therefore, required probability = $\frac{\mathrm{Number}\mathrm{of}\mathrm{students}\mathrm{who}\mathrm{don}\text{'}\mathrm{t}\mathrm{like}\mathrm{Kabbaddi}}{\mathrm{Total}\mathrm{number}\mathrm{of}\mathrm{students}}$
$$\begin{gathered} =\frac{65}{200} \\ =\frac{13}{40} \end{gathered}$$
Hence, the probability that the student selected dosen't like Kabbaddi is $\frac{13}{40}$.
