The Odds for 1 to 30
| Question | Answer |
|---|---|
| One number on a single pick | about 3.3% |
| The same number twice in a row | about 3.3% |
| Picks until a repeat is more likely than not | 7 |
| A given number at least once in 30 picks | about 64% |
A repeat becomes likely after only seven picks. On average, it takes about 120 picks to see every number at least once. If every student must go once, use elimination mode.
