世界杯夺冠赔率：巴法西3强并列第1 国足1赔501（世界杯冠军赔率出炉：巴西、法国、西班牙三强并列第一，国足1赔501）

Explaining betting odds

I’m thinking about breaking down what "1赔501" means and how to compare it to other odds. I need to calculate the implied probability and be cautious about bookmaker margins. Joint favorites could be around 5.00 odds, but I'm unsure about 巴法西's odds—it might be something like 5.5. I can show how to compute from odds, where 501 implies about 0.2%. I’ll aim to provide clear examples and maybe respond in Chinese, inviting the user to ask if they need more details!Drafting betting insights

I’m thinking about how to present the information clearly. First, I’d interpret that Brazil, France, and Spain are the top favorites, while China's championship odds are 501-1, indicating a very low probability, according to bookmakers.

Next, I’ll convert the odds into implied probabilities using the formula: p = 1/odds. So, 501 translates to about 0.20%. If the favorites are at 5.0 to 6.0, their implied probabilities would range from around 17% to 20%, though the total might slightly exceed 40-50% when combined.

I’ll also explain the margin and invite the user to provide odds if they want me to calculate for them!
