The main difference between American, British, and European odds is how they are shown. The US/UK odds are being written down as total winnings divided by the betting stake size (e.g., +135 or 3/2), while European odds are being expressed as decimal numbers (e.g., 1.85). However, in both cases, the odds determine the percentage probability of winning and the bookmakers’ revenue, and also lead to the same result either when winning or losing.
