Denote by En the convex hull of n points chosen uniformly and independently from the d-dimensional ball. Let Prob(d, n) denote the probability that En has exactly n vertices. It is proved here that Prob(d, 2d/2d-e{open})→1 and Prob(d, 2d/2d(3/4)+e{open})→0 for every fixed e{open}>0 when d→∞. The question whether En is a k-neighbourly polytope is also investigated.
