Let K be a d-dimensional convex body with a twice continuously
differentiable boundary and everywhere positive Gauss-Kronecker curvature.
Denote by Kn the convex hull of n points chosen
randomly and independently from K according to the uniform distribution.
Matching lower and upper bounds are obtained for the orders of magnitude of the
variances of the sth intrinsic volumes
Vs(Kn) of
Kn for s ∈ {1,...,d}.
Furthermore, strong laws of large numbers are proved for the intrinsic volumes
of Kn. The essential tools are the economic cap
covering theorem of Bárány and Larman, and the Efron-Stein
jackknife inequality.
