2010 AIME II Problem 2


A point PP is chosen at random in the interior of a unit square SS. Let d(P)d(P) denote the distance from PP to the closest side of SS. The probability that 15d(P)13\frac15\le d(P)\le\frac13 is equal to mn\frac{m}{n}, where mm and nn are relatively prime positive integers. Find m+nm+n.


Leading zeroes must be inputted, so if your answer is 34, then input 034. Full credit goes to MAA for authoring these problems. These problems were taken on the AOPS website.
