Abstract: | Let K be a convex body in ℝ
d
. It is known that there is a constant C
0 depending only on d such that the probability that a random copy ρ(K) of K does not intersect ℤ
d
is smaller than
\fracC0|K|\frac{C_{0}}{|K|} and this is best possible. We show that for every k<d there is a constant C such that the probability that ρ(K) contains a subset of dimension k is smaller than
\fracC|K|\frac{C}{|K|}. This is best possible if k=d−1. We conjecture that this is not best possible in the rest of the cases; if d=2 and k=0 then we can obtain better bounds. For d=2, we find the best possible value of C
0 in the limit case when width(K)→0 and |K|→∞. |
