Lei Gui-lin · Journal of Zhejiang University(Science Edition) · 2011
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.
