Calculating implied probability

I'm thinking about how to compute implicit probabilities from odds, like from 501:1 which comes out to about 0.199%. For top teams, it could be around 5-6%. I should provide a concise summary with helpful options, like explaining how betting odds work, showing an example calculation, and what "1赔501" means in terms of implied probabilities. It seems wise to avoid network calls until necessary, so I'll keep things straightforward and clear for the user with a breakdown of the information.Explaining odds conversion

I need to better describe how to convert decimal odds to implied probability, particularly with the Chinese expression "1赔501," which typically indicates decimal odds of 501.0. In this context, "1赔X" can mean net profit X for a 1 stake.

However, sometimes it creates confusion because, in this case, it likely refers to total return rather than just profit. I need to clarify that decimal odds are calculated by multiplying by the stake for total returns. It's essential to navigate these nuances to prevent misunderstandings.Clarifying sports odds in Chinese context

When looking at Chinese sports odds, "1赔4.50" clearly indicates decimal odds, while "1赔501" likely refers to decimal odds of 501.0, which includes the principal in returns. This can be a bit ambiguous, especially with the mention of odds like "国足世预赛出线赔率1赔6," which is definitely decimal.

For implied probability, using decimal odds, it's calculated as 1/501, giving about 0.1996%. If we consider it in fractional terms (501:1), it would be around 0.1992%, which are close enough to be practical. I'll present both formulas and note the importance of factoring in bookmaker margins, as the sum of implied probabilities typically exceeds 100%. Our next steps could involve fetching current odds or plotting changes over time.Formulating a user response in Chinese

I’m considering how to respond in Chinese with a concise and helpful explanation. I want to include a quick interpretation, explain the implied probability for China, and clarify what "巴法西" means along with why those three teams are joint favorites. I’ll also ask the user if they’re interested in more information, such as the latest odds for all teams, an implied probability table, or a probability chart. I won’t run any shell commands; this should be straightforward!
