AcademicMathematicsNCERTClass 9

To do:

We have to find the probability that a student of the class was born in August.

Solution:


Total number of students in the class $= 40$

Number of students born in August $= 6$

We know that,

Probability of an event=$ \frac{\text{ Number of favourable outcomes }}{\text { Total number of outcomes }}$

The probability that a student of the class was born in August $= \frac{6}{40}$

$= \frac{3}{20}$

The probability that a student of the class was born in August is $ \frac{3}{20}$.
