Abstract
Suppose we choose points uniformly randomly from a convex body in dimensions. How large must be, asymptotically with respect to , so that the convex hull of the points is nearly as large as the convex body itself? It was shown by Dyer-F\"uredi-McDiarmid that exponentially many samples suffice when the convex body is the hypercube, and by Pivovarov that the Euclidean ball demands roughly samples. We show that when the convex body is the simplex, exponentially many samples suffice; this then implies the same result for any convex simplicial polytope with at most exponentially many faces.
