Question

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.

Opinion	Number of students
like	135
dislike	65

Find the probability that a student chosen at random

(i) likes statistics, (ii) does not like it

Answer 1

Total number of students = 135 + 65 = 200

(i) Number of students liking statistics = 135

`"P(Students liking statistics) "=135/200=27/40`

(ii) Number of students who do not like statistics = 65

`"P(Students not liking statistics) "=65/200=13/40`
