Question

You have 15 pennies in your pocket. Of those pennies, 3 are Canadian. Suppose you pick a penny out of your pocket at random. Find P(not Canadian).

Answer 1

15 pennies total.....3 are Canadian...so (15 - 3) = 12 are not Canadian.

P(not Canadian) = 12/15 reduces to 4/5

Answer 2

12 is not canadian
so 12/15 which simplifies to 4/5 or 80% of choosing a non Canadian coin
