Its nearest twin

Shares 3 of 5 numbers (12, 19, 31) with the draw of 20 August 2010 — its closest relative in 352 draws. Chance gave a match this close a 97% likelihood somewhere in that history.

From the draw just before (24 March 2011): 12 carried over. Chance says 52% of draws repeat at least one number.

Sum and shape

The numbers add up to 99 — the 48th percentile of all possible tickets, around a middle of 100. Side-by-side numbers: 12–13. 44% of draws have at least one such pair.

The longest wait in this draw

24 had not appeared for 18 draws. A number waits about 8 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 1.3× as often as an average ticket — more popular than most. At 30 million tickets sold, a winner on these numbers would keep about 1% of the jackpot.
