Question

A bag contains 13 cards numbered 1 through 13. A card is randomly chosen from the bag. What is the probability that the card has an even number on it?

Write your answer as a fraction in simplest form.

Answer 1

6/13

Explanation:

since there are only 13 cards numbered 1 through 13, we have to count how many of these numbers are even.

1 2 3 4 5 6 7 8 9 10 11 12 13

Once you've figured out how many even numbers there are - in this case, there are 6 of them - then you put that number over the total number of cards, which is 13. So, you would get 6/13, which also happens to already be in simplest form.

hope this helps :)
