Its nearest twin

Shares 3 of 5 numbers (1, 19, 31) with the draw of 7 August 2010 — its closest relative in 719 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (29 March 2012): 37 carried over. Chance says 48% of draws repeat at least one number.

Sum and shape

The numbers add up to 94 — the 27th percentile of all possible tickets, around a middle of 110. No two numbers side by side. 40% of draws have at least one such pair.

The longest wait in this draw

19 had not appeared for 13 draws. A number waits about 9 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 1.1× as often as an average ticket — about as popular as most. At 30 million tickets sold, a winner on these numbers would keep about 3% of the jackpot.
