In poker, when someone goes all-in, and another player calls, they both reveal their cards, and on TV or internet poker websites, they show the percentage each player has of winning.
Player 1 has 2 Aces and goes all-in.
Player 2 has 2 Kings and calls.
Player 3 has 2 Aces but folds.
A 5, 6 and 9 come out on the flop. Then a King comes out.
Assuming there is no chance of a flush, does the computer show Player 1 having 0% chance of winning (by reading every single card that is dealt), or does it calculate it based on the known cards, and assume there's still 2 Aces in the remaining deck (because player 3's cards haven't been shown)?
Do the players in a tournament (in real life) know their win percentage, or do we just see it on TV?
