Lottery selections - Canada Lotto Max
In a lottery, or a raffle, numbers are usually selected from a pool of possible values in such a way that once a number has been chosen, it is no longer possible for it to be picked again. For example the balls in a lotto machine are removed one at at time, and there is no way for the same number to be picked twice. Similarly in a raffle, winning tickets are drawn and then discarded so that the same ticket cannot win twice.
