# 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.

Find the probability that a student chosen at random

(i) likes statistics,

(ii) does not like it.

**Solution:**

The probability of a certain event is given by the ratio of occurrence of a particular event by the total number of events.

Probability of students who like/dislike statistics = (Number of students who like/dislike statistics) / Total number of students

Total number of students = 200

Number of students who like statistics = 135

Number of students who dislike statistics = 65

**(i)** Probability of students who like statistics = 135/200 = 27/40

**(ii)** Probability of students who dislike statistics = 65/200 = 13/40
