Solution

Let's find the probability that a student is chosen at random likes statistics
Total number of students = $135 + 65 = 200$
Number of students who like statistics = $135$
The probability that a student likes statistics $= \frac{135}{200} = \frac{27}{40}$
Hence, the answer is $\frac{27}{40}$ .
