Find the probability stated in the problem.
A deck of cards contains 12 cards numbered I through 12. A card is randomly chosen from the deck what is the probability that the card has a number 5 or 7 on it? Write your answer as a fraction in simplest form.
If there are 12 cards with each number up to 12, there is an equal chance that any card could be chosen. (100/12=8) (8+8=16) 16% as a fraction is 4/25. Therefore, your answer is 4/25.
