Question

number is selected at random from the integers starting one to hundred then what is the probability that the selected number is not a perfect cube​

Answer 1

Answer:

0.96

Step-by-step explanation:

There are 100 numbers to choose from.

The number of perfect cubes though is only 4 (1³=1, 2³=8, 3³=24, 4³=64, but then 5³=125 is outside our set of numbers).

So to not get a perfect cube, there are 96 to choose from

P(not a perfect cube)

= ( # ways of not getting perfect cube ) / ( # ways of choosing a number)

= 96 / 100

= 0.96
