Calculate the payout on a parlay or accumulator bet.
Parlay odds multiply, so returns grow quickly while the probability of winning collapses just as fast. Four legs at even money give sixteen to one odds but only a one in sixteen chance. The bookmaker margin compounds across legs too, which is why parlays carry a far worse expected value than the same bets placed singly.
