According to this site:
- K♠️7♠️ beats A♠️2♠️ 39.10% of the time (and ties 0.62%).
- K♠️8♠️ beats A♠️2♠️ 38.71% of the time (and ties 0.61%).
Why is this?
I expected the two probabilities to be the same. My reasoning was: For any community cards such that K♠️7♠️ beats A♠️2♠️, we can replace all community 7's with 8's, and find an equally likely set of community cards such that K♠️8♠️ beats A♠️2♠️.
