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
To find the probability that the penny chosen is not Canadian, we need to determine the total number of non-Canadian pennies in your pocket and divide it by the total number of pennies in your pocket.
Since you have 15 pennies in total and 3 of them are Canadian, the number of non-Canadian pennies is 15 - 3 = 12.
Therefore, the probability of picking a non-Canadian penny is 12/15 = 4/5 or 0.8.
