Question

out of 100 students 25 students like maths find the probability that the students doesn't like maths​

Answer 1

$\huge{\mathfrak{\boxed{\blue{SOLUTION :}}}}$

Total no. of students = 100

No. of students who like maths = 25

Therefore,

No of students those who doesn't like maths = 100 - 25 = 75

Probability of the students who doesn't like maths = $\frac{75}{100}$ = $\frac{3}{4}$

Answer 2

Answer:

0.75, or 75%.

Step-by-step explanation:

The number of students which like Maths is 25, and the total's 100, so those that don't, are:

$n_{dl} = 100 - 25 = 75$

Now, probability that one randomly selected student doesn't like Maths, is given by:

$P(E) = \frac{favourable outcomes}{total outcomes} = \frac{75}{100} = \frac{3}{4}$

Or, $P(E) = 0.75$
