The company it keeps Seen most often with these — chance gives every partner about 45.5 shared draws, and the leaders are simply the ones that came out ahead this time.
It has shared a draw with every one of the other 25 numbers; chance expected about 0.0 still unmet by now. Every pair →
How many people play it Under the crowd model, 21 is picked about 1.22× as often as an indifferent choice — 14th most popular of 26. That changes nothing about whether it comes up, and everything about how many ways a jackpot on it would be shared.

Every draw it appeared in ← number 20 Every number number 22 → 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: 21 is drawn with probability 4/26 tonight whatever it did last week.
