Its nearest twin

Shares 3 of 5 numbers (1, 31, 33) with the draw of 17 June 2011 — its closest relative in 492 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (29 July 2011): nothing carried over. Chance says 54% of draws repeat at least one number.

Sum and shape

The numbers add up to 98 — the 54th percentile of all possible tickets, around a middle of 95. No two numbers side by side. 46% of draws have at least one such pair.

The longest wait in this draw

21 had not appeared for 21 draws. A number waits about 7 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 0.9× as often as an average ticket — about as popular as most. At 30 million tickets sold, a winner on these numbers would keep about 2% of the jackpot.
