Часто задаваемые вопросы

▾

How is random name selection done fairly?

Each name gets equal probability (1/n) using pseudo-random number generator. True randomness is algorithmic.

Can weighted selection be used?

Yes. If some names are more likely, adjust probabilities. Raffle: ticket quantity = probability weight.

Is a name picker better than drawing names?

Both fair if unbiased. Digital: audit trail, repeatable. Physical draw: perceived fairness, transparent process.
