We present an experimental study of jamming in the discharge of grains through an
opening in a two-dimensional silo. For a wide range of outlet sizes, we obtain the size distribution
of avalanche defined as the number of grains that fall between two consecutive jams. From these
distributions, we obtain the probability that the silo jams before N particles pass through the
orifice. Then a simple model of arch formation is proposed that predicts the shape of the jamming
probability function and reveals that it does not exist a critical size of the orifice above which
there is not jamming.
