Number 7

In Oz Lotto under the 7/45 + 2/45 · Jan 2009 – May 2022 rules — 697 draws, 7 from 1–45 (an earlier era).

135times drawn · chance expected 108 +2.78σ

5.2average wait between appearances · chance says 6.4

28longest completed wait · 75% chance of one at least that long

7 looks unusual on its own — and unremarkable among 45 numbers

Drawn 135 times in 697 draws against 108.4 expected, +2.78σ. Testing all 45 numbers at once means about 0.5 should look this way by luck alone, so the threshold tightens to 2.2e-4 and this does not pass it. It has also come out as the bonus ball 24 times, counted separately.

Where it lands in a sorted draw

Sort a draw and 7 has a favourite seat — chance gives a small number the low positions more often. That is the shape of sorting, not of the machine.

What this cannot tell you

Nothing here predicts the next draw. A number’s history is a record of a fair machine’s past, and the machine keeps none of it: 7 is drawn with probability 7/45 tonight whatever it did last week.
