Pick two points uniformly at random inside a regular n-gon. For even n≥4, the probability that the line containing these points will pass through any pair of opposite edges of the polygon is:

8/(3n)

Pick two points uniformly at random inside a regular polyhedron with F faces. For even F, the probability that the line containing these points will pass through any pair of opposite faces of the polyhedron is:

3/F
