To know the opinion of the students about the subject statistics, a survey of 200 students was conducted. The data is recorded in the following table.
OpinionNumber of students
like135
Dislike65

Find the probability that a student chosen at random
i) likes statistics
ii) does not like it.


Answer :

Total number of students
= 135 + 65 = 200

i) Number of students liking statistics = 135
\(P = \frac{135}{200} = \frac{27}{40}\)

Therefore, the probability of student liking statistics is \(\frac{27}{40}\)

ii) Thus, Probability of students that students dont like statistics is
\( = P = 1 - \frac{135}{200} = \frac{65}{200} = \frac{13}{40}\)

Therefore, the probability of student not liking statistics is \(\frac{13}{40}\).
