Here are some basic poker probabilities that you should know:

Flush Probabilities:

• Probability of being dealt suited cards 23.5%

• Probability of flopping a flush when holding two suited cards 0.8%

• Probability of flopping a flush draw when holding two suited cards 10.9%

• Probability of hitting a flush draw (both turn/river, needing one card to hit) 35%

Straight Probabilities:

• Probability of hitting an open-ended straight draw (i.e. 4 straight cards, need one on either end to hit on turn or river) 31.5%

• Probability of hitting a gutshot draw (inside straight draw) on turn or river 16.5%

Pocket Pair Probabilities:

• Probability of being dealt a pocket pair 5.9%

• Probability of hitting a three of a kind or quads at the flop when you hold a pocket pair 11.8%

• Probability of being dealt AA 0.45%

Unpaired Hole Cards Probabilities:

• Probability of making a pair with one of your hole cards (example: hitting an ace or a king if you hold AK) 32.4%

• Probability of hitting two pair on the flop with each of your hole cards (example: hitting both an ace and a king on the flop, when holding AK) 2%

Ace Probabilities:

• Probability that at least one of your hole cards is an ace 14.9%

• Probability of no one holding an ace, assuming you do not have an ace. Note: this can be used for any card (because the chances of you being dealt an ace or a king is exactly the same).
