Its nearest twin

Shares 4 of 6 numbers (4, 9, 10, 20) with the draw of 7 February 2011 — its closest relative in 269 draws. Chance gave a match this close a 65% likelihood somewhere in that history.

From the draw just before (21 December 2011): 10 carried over. Chance says 71% of draws repeat at least one number.

Sum and shape

The numbers add up to 63 — the 2th percentile of all possible tickets, around a middle of 108. Side-by-side numbers: 9–10. 63% of draws have at least one such pair.

The longest wait in this draw

4 had not appeared for 8 draws. A number waits about 6 on average, and a wait this long was not a signal — the machine has no memory of it.

How many people held it

A line like this is played about 2.3× as often as an average ticket — more popular than most. At 30 million tickets sold, a winner on these numbers would keep about 2% of the jackpot.
