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!

看起来是一条赔率新闻：巴西/法国/西班牙三队并列头号热门，国足夺冠为“1赔501”。

快速解读

• “1赔501”是十进制赔率，隐含概率约为 1/501 ≈ 0.20%（未扣水，实际更低）
• 三队并列第1通常意味着各自赔率接近（常见在5.0–6.0区间）；例如：
  • 5.0 → 隐含概率 1/5.0 = 20%
  • 6.0 → 隐含概率 1/6.0 ≈ 16.7%
• 赔率包含水钱（庄家边际），多队热门的隐含概率加总会>100%，真实概率应当再按水钱等比例压缩
• 赔率会随分组、伤病、赛程和交易量动态调整，离比赛越近越敏感
