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 statistics.

Answer 1

Total number of students $=135+65=200$

(i) Number of students like statistics $=135$

$Probability=\frac{135}{200}=\frac{27}{40}$

(ii) Number of students who don't like statistics $=65$

$Probability=\frac{65}{200}=\frac{13}{40}$
