Question

a number is selected at random from integer 1 to 100 find the probability that it is not in perfect cube

Answer 1

96/100 is the probability

Answer 2

No of integers which are perfect cubes in 1-100 = (1,8,27,64) = 4
Therefore 96 integers are not perfect cubes.
Total number of integers is 100
Therefore-
Probability = 96/100
= 24/25.
