Lyle puts balls numbered 1 through 75 into a bag with 75 other balls of the same size but without numbers. Min puts balls numbered 1 through 75 into a different bag with 125 other balls of the same size but without numbers. If Lyle and Min each select a ball at random from their respective bags, what is the probability that the 2 balls selected will have numbers that are the same?
