Detailed Solution

Given a data about the poll of 200 students.
Question Image

We have to find the probability that a student chosen at random does not like Mathematics.
The probability of an event A is given by,

P (A) = Number of favourable outcomes T o t a l number of outcomes

Total number of students,

n (S) = 200

.
Let

B

be the event that students do not like mathematics. .
Number of students who do not like mathematics,

n (B) = 65

.
Then,
The probability that a student does not like Mathematics is given by,

P (B) = n (B) n (S)

⇒ P (B) = 65200 ⇒ P (B) = 1340 ⇒ P (B) = 0.325

Thus, the probability that students who do not like Mathematics is

0.325

Hence, option 3 is the correct option.
