The percentage of attandance of different class in a year in a school is given below:
ClassXIXVIIIVIIVIVAttendance306285927655
What is the probability that the class attendence is more than 75%?
Percentage of attendance of different classes
ClassXIXVIIIVIIVIVAttendance306285927655
Total attendance more than 75% (m) =VIII,VII and VI =3 classes and total number of classes(n)=6
∴ Probability P(A) 36=12
