Two points P,QP,Q are chosen uniformly at random from the interior of the square ABCDABCD. The line L1L_1 through PP and QQ is drawn. The probability that the points AA and CC are on different sides of L1L_1 can be expressed as ab\frac{a}{b} where aa and bb are coprime positive integers. What is the value of a+ba + b?
