In the xy-plane, a triangle has vertices (0,0), (4,0) and (4,8)

In the xy-plane, a triangle has vertices (0,0), (4,0) and (4,8). If a point (a,b) is selected at random from the triangular region, What is the probability that a-b>0?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
