কীভাবে Name Picker গণনা করবেন
Name Picker কি?
A random name picker selects one or more names at random from a list — useful for prize draws, assigning tasks, picking teams, or choosing a winner fairly.
সূত্র
Random selection algorithm: each name probability = 1/n (uniform); weighted if importance varies
- n
- Number of names in list
- P
- Probability of selection (1/n)
ধাপে ধাপে নির্দেশিকা

Each name has exactly 1/50 = 2% chance of being selected
সচরাচর জিজ্ঞাসা
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.
