摘要
利用平面角的概念研究了正常凸多边形一边着地的概率,进一步利用立体角的概念研究了正常凸多面体一面着地的概率并举例进行了计算.
the probability of the normal convex polygon＇s one side tailing 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.
