Question

In a survey, out of 200 students, it is observed that 125 students like mathematics. What is the probability that the students who do not like mathematics is :

• A. $\frac{5}{8}$
• B. $\frac{7}{8}$
• C. $\frac{3}{8}$
• D. $\frac{1}{2}$

Answer 1

The correct option is C $\frac{3}{8}$

$200$ students, it is observed that $125$ students like mathematics.

So the number of students who don't like mathematics are $200-125=75$

Therefore the probability that the students who do not like mathematics is $P\left(E\right)=\frac{75}{200}=\frac{3}{8}$
