A bag contains 15 balls numbered 1 through 15. What is the probability of selecting a ball that has an even number when one ball is drawn from the bag?
Out of the 15 balls, there are 7 balls that have an even number (2, 4, 6, 8, 10, 12, and 14). Therefore, the probability of selecting a ball that has an even number is 7/15.
