An integer number is chosen at random from the first 100 integers. What is the probability that the chosen number is a perfect cube?

1/25

The correct answer is Option (4) → 1/25

The first 100 integers are from 1 to 100.
Perfect cubes within this range are 1, 8, 27, and 64.
So, there are 4 perfect cubes out of 100 integers.

Probability = number of favourable outcomes divided by total outcomes
= 4 /100
= 1/25
