The PokerNews Quiz: Probabilities on the Flop

02-24-2018 6009 responses Top results

You know about "flop props," yes? Hold'em players adding a bit of extra action to the game by betting whether the next flop will contain a pair. Or three cards in sequence. Or arrive all red or all black.

Knowing the probabilities associated with flops can help such prop bettors have an edge when making such wagers. Such knowledge can sometimes help more generally as far as understanding the likelihood of certain board textures arriving with those first three community cards.

Here's a quick quiz containing eight multiple-choice questions testing your knowledge of probabilities on the flop. (Note: all the probabilties cited below have been determined without taking into account anyone's hole cards first.)

Get six of eight right and you pass the quiz, and when done check out the "Top results" to see how you did versus others. If logged in here at PokerNews, your username will appear. Need an account? Click here to get one.
