How many numbers different draws share, compared with chance. What does this mean?
Statistics only use draws from one rule set, because games with different numbers cannot be compared.
Small sample: with fewer than 200 draws, big swings are normal and tell you very little.
| Shared numbers | Pairs of draws | Chart | Expected by chance |
|---|---|---|---|
| 0 | 835 | 831.1 | |
| 1 | 349 | 346.3 | |
| 2 | 38 | 45.4 | |
| 3 | 3 | 2.2 | |
| 4 | 0 | 0 | |
| 5 | 0 | 0 |
The bars use a square-root scale so the rare rows stay visible.
We compared every draw with every other draw (1,225 pairs) and counted the white numbers they share. The expected column is what pure chance predicts, so a result close to it means the draws behave like random draws.
No two draws share 4 or more white numbers in this period.
No two draws have ever had the same five white numbers in the same game rules, which is what you would expect for such a large number of combinations.
