When Johnny throws darts, his accuracy is always off. (If he aims at something, the dart can go as far as 20cm away from the intended point in any direction.) If he goes to a circus and to a balloon popping station, where the balloons are blown up to 20cm in diameter, what is the probability that he will hit the balloon if he aims at the center?
