A 3-to-1 underdog — bet $100 to win $300. At 25% implied probability, this is a longshot but not unreasonable. Common on UFC underdogs and futures markets.
At +300 odds, the implied probability is 25.0%. A $100 bet returns $400.00 total — that's $300.00 profit plus your $100 stake.
In decimal format, +300 equals 4.00. In fractional format, it's 3/1. And in American format, it's +300.
