The Odds for 1 to 16
| Question | Answer |
|---|---|
| One number on a single pick | 6.25% |
| The same number twice in a row | 6.25% |
| Picks until a repeat is more likely than not | 5 |
| A given number at least once in 16 picks | about 64% |
Five picks is enough for a repeat to be more likely than not. That is the birthday paradox. If every slot must be used exactly once, use elimination mode so each winner leaves the list.
