Its nearest twin

Shares 4 of 5 numbers (4, 11, 19, 27) with the draw of 28 May 2010 — its closest relative in 679 draws. Chance gave a match this close a 45% likelihood somewhere in that history.

From the draw just before (20 February 2012): nothing carried over. Chance says 63% of draws repeat at least one number.

Sum and shape

The numbers add up to 90 — the 74th percentile of all possible tickets, around a middle of 78. No two numbers side by side. 54% 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 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 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 0% of the jackpot.
