No. of Students 3 5 25 7
A student is to be selected randomly from his class for some competition. The probability of selection of the student is highest whose weight is in the interval _________. Fill in the blanks to make the statement true.

Solution:

Given, the table represents the number of students and their weight.

A student is to be selected randomly from his class for some competition.

The probability of selection of the student is highest whose weight is in the interval _________.

We have to fill in the blanks to make the statement true.

From the table,

Number of students with weight range 44-47 = 3

Number of students with weight range 48-51 = 5

Number of students with weight range 52-55 = 25

Number of students with weight range 56-60 = 7

We observe a maximum number of students is 25.

The weight range of students is 52 - 55.

Therefore, The probability of selection of the student is highest whose weight is in the interval 52-55.
