En "coke hand" består av 13 kort der kortverdiene ligger i intervallet 2-9. M.a.o. kan kortene i en "coke hand" velges blant 8*4=32 kort i en kortstokk på 52 kort. Dermed blir sjansen for å trekke en slik hånd
C(32,13) / C(52,13) = [32!/(19!*13!)] / [52!/(39!*13!)] = (32!*39!) / (19!*52!) ≈ 5,5*10[sup]-4[/sup].
C(32,13) / C(52,13) = [32!/(19!*13!)] / [52!/(39!*13!)] = (32!*39!) / (19!*52!) ≈ 5,5*10[sup]-4[/sup].
