Why parlay odds multiply

Parlay odds are the product of each leg's decimal odds. The catch: the implied probability of hitting all legs is the product of each leg's probability — so a 3-leg parlay of -110 bets has roughly a 1-in-8 chance, not the "big payout" the headline suggests. This tool shows you the real number.
