| Abstract: | The probability of the abnormal convex and concave polygon boards's every side falling to the ground has been deduced by study the characteristic of their falling to the ground.Furtherly the probability of the abnormal convex and concave polyhedron's every face falling to the ground has been studied by solid angle. |
| Keywords: | abnormal convex polygon board concave polygon board concaxe polyhedron abnormal convex polyhedron least concaxe become polyhedron probability |
