Question

An integer is chosen at random between 1 and 100. Find the probability that it is:

Answer 1

Total no. of outcomes - 100
1) Favorable outcome ( divisible by 8 ) - 12/100 - 3/25
2) Favorable outcome ( not divisible by 8 ) 1- 3/25 or 88/100 - 22/25

hope it will help you☺

Answer 2

a) total outcomes =100
the favourable outcomes (divisible by 8)=12
the probability of getting a number divisible by8=12/100=3/25


the probability of getting a number indivisible by 8=
=1-3/25
=22/25
