उत्तर
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
