Probability — geometric probability on a unit square

A point (x,y)(x,y) is to be selected from the square SS containing all points (x,y)(x,y) such that 0≤x≤10\le x\le1 and 0≤y≤10\le y\le1. What is the probability that the selected point belongs to subset of points such that 0.5<(x+y)<1.50.5<(x+y)<1.5?
