Unequal probabilities

Weighted Random Picker

Use weights only when entries are intentionally meant to have different chances. Enter each line as label|weight and review the first-draw probability before selecting unique winners without replacement.

Good uses for weighted selection

  • Allocate options in proportion to documented capacity or priority.
  • Practice probability with a visible list of relative weights.
  • Choose several distinct outcomes while preventing the same line from winning twice in one run.

Set up a transparent weighted draw

  1. Give every entry a clear label and a positive numeric weight.
  2. Review the probability table and confirm that duplicate labels or accidental zeros are not hiding in the list.
  3. Choose the winner count, run the picker, then copy the result if you need an external record.

Limits and audit cautions

  • Weights are relative: 2 and 1 mean the same probabilities as 20 and 10.
  • After each winner is removed, the remaining probabilities change for the next draw.
  • The page does not verify list ownership, participant eligibility, or compliance with sweepstakes rules.

Weighted picker questions

What does a weight of 5 mean?
It means five shares of the total first-draw weight, not a guaranteed five wins.
Can one entry win twice?
Not within the same multi-winner run; winners are sampled without replacement.
Are decimal weights allowed?
Yes. Any positive finite value is accepted, and only the ratio between weights matters.
