| Abstract: | the probability of the normal convex polygon's one side falling to the ground has been studied by planc angle,furtherly the probability of the normal convex polyhedron's one face falling to the ground has been studied by solid angle,at the same time,the example that has been carried on the calculation of the probability is given. |
| Keywords: | normal convex polygon normal convex polyhedron plane angle solid angle probability |
