Decimal (2.50): your total return per 1 unit staked, stake included.
Fractional (3/2): profit per unit staked. 3/2 means 3 profit for every 2 staked.
American (+150 / −200): a plus number is the profit on 100 staked; a minus number is what you stake to win 100.
Probability: 100 ÷ decimal odds. It's the chance the price implies, before removing the bookmaker's margin.
