Topics: [[Mathematics]] Randomness is truly random. However, people generally don't want truly random. Weighted random can be accomplished by biasing a [[Percents|Percentage]] of the results to one time, modifying the distribution. ## Random without Replacement Random without replacement means that you pick randomly from the pool of unselected items, until it's exhausted. A good way to think of it is randomly taking items out of a bag, until the bag is empty. Then you fill the bag up again. --- # References
