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 ...
Pigeon keeping or pigeon fancying is the art and science of breeding domestic pigeons. People have practiced pigeon keeping for at least 5,000 years [1] and in almost every part of the world. In that time, humans have substantially altered the morphology and the behaviour of the domesticated descendants of the rock dove to suit their needs for ...
