Re: Odds for opponent to hit same flush
The odds you are looking for depend on the number of your opponents. The complete formula is too heavy. I will give you some partial results:
For 7 opponents, the odds for at least one of them to...

Re: How often will the board pair
I will show you the calculation of odds for the flop being unpaired. Then, you will do (1- calculated odds) for the opposite event (flop to be paired).
-From outside view (no pocket cards seen):...

Re: Odds of open-ended straight improving
First of all, 41% is incorrect, indeed.
Although your calculations are mostly incorrect, you have reached a result pretty close to real odds.
Your event "hitting on river" is ambiguously defined....

Re: Tricky and Confusing Question
First of all, you have 3 kings left, not 4, if you hold one.
If you refer to your turn odds (odds of hitting A or K by turn), the calculus should be performed as 5/47 = 10.64%.
If you refer to the...

Re: Simple Probability Question
You have to be more specific. Where your 21 outs come from? Maybe you are double-counting some situations (i.e your events to measure are not mutually exclusive). Or you are not correctly apply the...

Re: Probablity Question for Advanced Players
That reverts to calculate combinations (this is the easisest and shortest way in figuring out the odds). In your example: you hold AJ, flop: K37.
The odds for straight (10 Q needed):

Re: Using Math to Beat Poker
Math reverts to probabilities in gaming strategy. While the probabilities are estimations (measurements) and not certainties, the math you use becomes relative regarding a certain win. If you choose...

Re: The purity of probability?
You have to define "pure" for a precise answer.
Probability is just a measurement. It measures events, but it not provides any certainty about them. It has his own rigorousness, because is...

Re: more difficult question
Your reasoning is correct, but your probability calculus is wrong.
Using combinations in such calculations spares you of a lot of errors. So:
The favorable 4-card combinations for that event are:...

Re: Odds for flopping two pair?
The event to be measured is "flopping two pair". I think this should also include two pair with new pair on the flop. Your calculation was only made for two pair using both of hole cards.
So: if you...

Re: Calculating odds
Your calculation starts with an error: the number of possible flops is C(50,3)=19600 (this is 50*49*48/6). When you multiply 50*49*48 you are doble-counting a lot of combinations. When calculating...

Re: easy one - prob of trips from one card
For the flop:
favorable combinations for trips or quads:
(AAx) - C(3,2)*46=138
(AAA) - C(3,3)=1
Totally, you have 139 favorable combinations from C(50,3) = 19600 possible. So, the odds are...

Re: Good books on Hold\'em math (odds) ?
I have the book and I find it very useful. Maybe the bad responses you mentioned come from people scared about the math. It also has favorable reviews on Amazon.

While the first is just perfect for a...

Re: odds of two people getting dealt AA?
If you are dealt AA, the odds of someone else being dealt AA are n/C(50,2) = n/1225, where n is the number of your opponents.

Re: Chance of hitting a hand on the flop
Odds of hittting 3 unique cards (for a straight flush, for example): 1/C(50,3) = 1/19600
Odds of hitting a specific suit (when you hold two of this suit): C(11,3)/C(50,3) = 165/19600 = 0.841%
