Abstract
The distribution function for the current noise in a normal-metal-supe rconductor quantum point contact is calculated. It is shown that this distribution describes independent processes when a charge +/-e0 or +/ -2e0 passes through the contact. At low temperature and voltage only p rocesses with double-charge transfer are relevant. At zero temperature and low voltage the distribution has a binomial form.
