In probability theory and statistics, the discrete uniform distribution is a symmetric probability distribution whereby a finite number of values are equally likely to be observed; every one of n values has equal probability 1/n. Another way of saying 'discrete uniform distribution' would be 'a known, finite number of outcomes equally likely to happen'.
