Answer:
Total no. of favourable outcomes of getting a perfect square no. = 10 i.e
(1,4,9,16,25,36,49,64,81,100)
(i)Probability that it is a perfect
square = 10/100 = 1/10
(ii) Favourable outcomes of getting perfect cube = 4 i.e (1,8,27,64)
Probability of getting perfect cube = 4/100 = 1/25
Therefore, probability of getting that it is not a perfect cube = 1- 1/25
= 25-1/25 = 24/25
