Ex 15.1, 3
In a particular section of Class IX, 40 students were asked about the months of their birth and the following graph was prepared for the data so obtained. Find the probability that a student of the
class was born in August:
Number of students born in the month of August = 6
Total number of students = 40
P (Students born in the month of august)
= (ππ’ππππ ππ π π‘π’ππππ‘π ππππ ππ ππ’ππ’π π‘)/(πππ‘ππ ππ’ππππ ππ π π‘π’ππππ‘π )
= 6/40
= 3/20
