We study the asymptotics of the hyperbolic lattice-counting problem for $\G$ under restrictions imposed by the modular symbols $\modsymγ{\a}$. We prove that the normalized values of the modular symbols, when ordered according to this counting, have a Gaussian distribution.14 pages, submittedNumber Theory11F67 (Primary); 11F72, 11M36 (Secondary)text
