Dislike | 65 |

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 \(\frac{13}{40}\).
