Abstract
We prove that with probability tending to 1, a one-relator group with at least three generators and the relator of length n is residually finite, is a virtually residually (finite p-)group for all sufficiently large p, and is coherent. The proof uses both combinatorial group theory and non-trivial results about Brownian motions.
