Edx概率课程象棋锦标赛概率问题Part C求解困惑

Hey there, I feel your pain—there’s nothing more frustrating than getting stuck on a probability problem, especially when the course is archived and you can’t hit up the TA for help. Let’s break this down together so we can figure out why your answer isn’t matching the standard solution.

To help you pinpoint the issue, could you share a bit more detail? Here’s what I’ll need to work through this with you:

• The full, complete text of Part C of the problem (you cut off the rule about Al retaining his championship—fill that in, plus any other specifics like win probabilities for each player, tie-breaker rules if they exist, etc.)
• A walkthrough of your approach: how you defined the events, which probability rules you applied, and step-by-step calculations you did to get your answer
• The standard solution (either the final numerical answer or the key steps they used to get there)

Once you have those details, we can dig into whether it’s a misinterpretation of the tournament rules, an oversight in calculating all possible outcomes, or a simple arithmetic error that’s throwing things off.
