Number 15

In Texas Two Step under the 4/35 + 1/35 · since Sep 2025 rules — 109 draws, 4 from 1–35.

4times drawn · chance expected 12 −2.55σ

2draws waiting · a wait this long: 89% for any number

26.3average wait between appearances · chance says 8.8

50longest completed wait · 0.8% chance of one at least that long

15 looks unusual on its own — and unremarkable among 35 numbers

Drawn 4 times in 109 draws against 12.5 expected, −2.55σ. Testing all 35 numbers at once means about 0.4 should look this way by luck alone, so the threshold tightens to 2.9e-4 and this does not pass it.

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: 15 is drawn with probability 4/35 tonight whatever it did last week.
