Question

The percentage of attendance of different classes in a year in a school is given below :
What is the probability that the class attendance is more than 75%?
A. 1/6
B. 1/3
C. 5/6
D.1/2

Answer 1

The probability that the class attendance is more than 75% is 1/2

Option B is correct.

The complete data is,

Class                 X        IX       VIII      VII      VI      V

Attendance      30       62      85       92      76     55

From given data, we can conclude that,

the class with highest   attendance is class VII

and the class with lowest   attendance is class X

total number of classes are 6 (X        IX       VIII      VII      VI      V)

A total number of classes that have attendance of more than 75% are 3

class VIII with 85% attendance

class VII with 92% attendance

class VI with 76% attendance

The probability that the class attendance is more than 75% is,

P(A) = 3/6 = 1/2

∴ P(A) = 1/2
