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.
