Its nearest twin

Shares 2 of 4 numbers (72, 75) with the draw of 12 January 2015 — its closest relative in 790 draws. Chance gave a match this close a 100% likelihood somewhere in that history.

From the draw just before (25 April 2015): nothing carried over. Chance says 20% of draws repeat at least one number.

Sum and shape

The numbers add up to 192 — the 79th percentile of all possible tickets, around a middle of 156. No two numbers side by side. 15% of draws have at least one such pair.

The longest wait in this draw

72 had not appeared for 43 draws. A number waits about 19 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 5% of the jackpot.
