A probabilistic generalization of the pigeonhole principle states that if n pigeons are randomly put into m pigeonholes with uniform probability 1/m, then at least one pigeonhole will hold more than one pigeon with probability. where (m)n is the falling factorial m(m − 1) (m − 2)... (m − n + 1). For n = 0 and for n = 1 (and m > 0), that ...
