In statistical mechanics, the radial distribution function represents the distribution of interparticle separations [1]. This Demonstration shows the results of *exact* statistical-mechanical computations of the radial distribution functions for a one-dimensional binary system of particles interacting via hard-rod potentials [2, 3].
