A lottery game has balls numbered 1 through 15. If a ball is selected at random, what is the probability of selecting a ball showing an even number or the number 12?

I thought the answer would be 7 even numbers and 1 for the 12 which would be 8/15 is not an option for the answer.
Our choices are 5/4,7,4/5,7/15
