Question

You have the numbers 1–25 written on slips of paper. If you choose one slip at random, what is the probability that you will select a number that is divisible by 3

Answer 1

Probability = (number of possible successes) / (total possible results)

Successes . . . you pull out 3, 6, 9, 12, 15, 18, 21, or 24 . . . 8 possible successes

Total possible results . . . 25

Probability = 8 / 25 = 32%
