Distribution of the number of vertices of a regular simplex. (Russian) Zbl 0626.60019
The authors compute for \(n=3\) and \(k=1,2,3\) the probability that exactly k vertices of the n-dimensional simplex are over a random hyperplane, drawn through its centroid. The randomness is introduced by the assumption that the normal vector of the hyperplane is uniformly distributed on the surface of the unit n-dimensional sphere.
