Question

a number is selected at random from integer 1 to100 find the probability that is a) a perfect square b) not a perfect cube
​

Answer 1

Answer:

Sample space = 100

Favourable events = ,1,4,9,16,25,36,49,64,81,100= 10

Probability = 10/100=1/10

unfavorable events = 1,8,27,64=4

Favourable events = 100-4= 96

Probability = 96/100
