The longest wait in this draw

12 had not appeared for 4 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 1.5× 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.
