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

Find the probability that a student chosen at random 

(i) likes statistics, 

(ii) does not like it

Answer 1

(i) P (a student likes statistics) = No. of students who like statistics/ Total no. of students = 135/ 27 = 200/ 40

(ii) P (a student does not like statistics) = No. of students who do not like statistics/ Total no. of students 

= 65/13 

= 200/ 40
