Câu hỏi thường gặp

Q

How is random name selection done fairly?

A

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

Q

Can weighted selection be used?

A

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

Q

Is a name picker better than drawing names?

A

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