You have the numbers 1–24 written on slips of paper. If you choose one slip at random, what is the probability that you will NOT select a number divisible by 3?

The numbers from 1-24, which are divisible by 3 are : 3,6,9,12,15,18,21,24 = 8 options

There are 24 possible slips to choose
So there are 16 possible options that are not divisible by 3

P(divisible by 3) = 8 / 24
P(not divisible by 3) = 16 / 24 = 16 / 24 = 2/3
