According to the given question -
Number of students given on y - axis
Names of Months given on x - axis
Total strength of class 9 = 40
Number of students born in August = 6 .
Finding the probability that a student of class was born in August -
Probability that a student of class was born in August = 6/40
Simplifying by 2
2 x 3 = 6
2 x 20 = 40
= 6/40
= 3/20
Hence : Required Answer is 3/20
