Solved

Let us consider the class of groups with $n$ generators and $m$ relators. A subclass of this class is called dense if the ratio of the number of presentations of the form $\langle a_1, \dots, a_n \mid R_1, \dots, R_m \rangle$ (where $|R_i| = d_i$) for groups from this subclass to the number of all such presentations converges to 1 when $d_1 + \dots + d_m$ tends to infinity. Prove that for every $k < m$ and for any $n$ the subclass of groups all of whose $k$-generator subgroups are free is dense.

Progress

This is proved (G. N. Arzhantseva, A. Yu. Olshanskii, Math. Notes, 59, no. 4 (1996), 350–355).
