Question

The percentage of attandance of different class in a year in a school is given below:

$\begin{matrix} Class & X & I X & V I I I & V I I & V I & V Attendance & 30 & 62 & 85 & 92 & 76 & 55 \end{matrix}$

What is the probability that the class attendence is more than 75%?

Solution

Percentage of attendance of different classes

$\begin{matrix} Class & X & I X & V I I I & V I I & V I & V Attendance & 30 & 62 & 85 & 92 & 76 & 55 \end{matrix}$

Total attendance more than 75% (m) =VIII,VII and VI =3 classes and total number of classes(n)=6

$∴$ Probability P(A) $\frac{3}{6} = \frac{1}{2}$
