It's random. By definition there exists a statistical possibility that numbers will repeat. It's possible that you can add 10 random integers from 1-10 to a list and that they wouldn't repeat, but it would be unlikely.

Ideally, each time you call a randomization function, you have exactly the same odds of getting any one number as you do of getting any other number, including the number you got last time.
