Question

At a carnival game, a large horizontal board has 20 holes of the same size cut in it. For the game, you toss a ball onto the board and it lands or rolls into one of the holes. The board is surrounded on all sides, so the ball is certain to fall in a hole. Three of the holes will earn a small prize and one of the holes will earn a large prize. If Grady buys a ticket for one ball that he'll toss on the board, what is the probability that he'll win a prize?\
5%
15%
