Never drawn alongside 7 of the other 34 numbers; chance expects about 7 such strangers by now. Every pair →
How many people play it
Under the crowd model, 13 is picked about 0.92× as often as an indifferent choice — 31st most popular of 35. That changes nothing about whether it comes up, and everything about how many ways a jackpot on it would be shared.
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: 13 is drawn with probability 4/35 tonight whatever it did last week.
