That means that if you intend to repeat an experiment until the first success, then, given that the first success has not yet occurred, the conditional probability distribution of the number of additional trials does not depend on how many failures have been observed.
Isto significa que se intentamos repetir o experimento ata o primeiro éxito, entón, dado que o primeiro éxito aínda non ocorreu, a distribución da variable condicionada do número de ensaios adicionais non depende de cantos fallos se observaron.
