Question

Matthew had exactly 20 pennies in his pocket. Five were Canadian pennies and the rest were U.S. Pennies. If he took 1 penny out of his pocket at random, what are the odds that the penny would be Canadian?

Answer 1

1/4

This is also same as 0.25

Explanation:

Probability is the ratio of the number of possible outcomes to the total outcome.

Given that there are 20 pennies and 5 were Canadian pennies, this means that the number of American pennies

= 20 - 5

= 15

If one penny is taken out of his pocket at random, the probability or odds that it would be a Canadian penny P(C)

= 5/20

= 1/4 (To the lowest term)

= 0.25 ( in decimal)
