Its nearest twin

Shares 3 of 5 numbers (13, 16, 21) with the draw of 1 July 2010 — its closest relative in 108 draws. Chance gave a match this close a 81% likelihood somewhere in that history.

From the draw just before (24 July 2010): nothing carried over. Chance says 57% of draws repeat at least one number.

Sum and shape

The numbers add up to 100 — the 71th percentile of all possible tickets, around a middle of 88. No two numbers side by side. 49% of draws have at least one such pair.

The longest wait in this draw

21 had not appeared for 13 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 1.0× as often as an average ticket — about as popular as most. At 30 million tickets sold, a winner on these numbers would keep about 1% of the jackpot.
