Probability as an integral Two points P and Q are chosen randomly, one on each of two adjacent sides of a unit square (see figure). What is the probability that the area of the triangle formed by the sides of the square and the line segment PQ is less than one fourth the area of the square? Begin by showing that x and y must satisfy xy < \(\frac{1}{2}\) in order for the area condition to be met.
