Probability theory talks about events which occur with a given (possibly unknown) probability. Usually, when it talks about several events occurring, it assumes that if one event occurs, this does not change the probablility of the other events occurring. Abraham de Moivre wrote: Two Events are independent, when they have no connexion one with the other, and that the happening of one neither forwards nor obstructs the happening of the other.
