the tag was created, deleted(?), and then re-created with a typo, and it does not let me change it. (it says something alike 'the randomized-algorithms cannot be created since randomized-algorithm already exists.. raise this issue in meta')
I'll take this opportunity to discuss randomness-related tags.
I don't see how randomized-algorithms applies to this question: it's about generating random numbers. A randomized algorithm is one that uses random numbers, not one that makes them: quicksort pivot, probable primes, …
This question should be tagged random-number-generator: although it's not about a PRNG per se, it's about generating random numbers with a particular distribution.
