There are eight lockers in a school hallway and five of them have star stickers on the inside. If the first locker opened does not have a star in it, what is the probability that the second won’t either?

5/7. You are eliminating one of the 8 original lockers yet you still have 5 possible stars left. Hence a probability of 5 stars over 7 possible lockers left. 5/7 = .7143 or 71.43 %
