Answer:
6/13
Step-by-step 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 :)
