text: For an absolutely continuous probability measure μ on Rd and a nonnegative
integer k, let sk(μ, 0) denote the probability that the convex hull of k+d+1 random
points which are i.i.d. according to μ contains the origin 0. For d and k given,
we determine a tight upper bound on sk(μ, 0), and we characterize the measures
in Rd which attain this bound. This result can be considered a continuous analogue
of the Upper Bound Theorem for the maximal number of faces of convex polytopes
with a given number of vertices. For our proof we introduce so-called h-functions,
continuous counterparts of h-vectors for simplicial convex polytopes.
