Question

Rohit collected the data regarding weights of students of his class and prepared the following table:

Weight (in kg)	44 – 47	48 – 51	52 – 55	56 – 60
Number 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 ______.

Answer 1

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 52 – 55.

We know that,

Probability = `"Number of favourable outcomes"/"Total number of possible outcomes"`

∴ To make the probability highest, we have to take the interval where number of students, i.e. possible outcomes are highest.

Here, the probability is highest whose weight is in the interval
