On a hyperbolic surface, a closed geodesic is said to be simple if it does not intersect itself, and a multi-geodesic is a disjoint union of simple closed geodesics. In this talk, I will explain how to pick a random multi-geodesic, and present an attempt to answer the following question: what is the shape of a random multi-geodesic on a hyperbolic surface of large genus? In particular, we will see that the average lengths of the first three largest connected components of a random multi-geodesic on a large genus hyperbolic surface is approximately,
75.8%, 17.1%, 4.9%, respectively, of the total length. This is joint work with Vincent Delecroix.
