How to calculate Poker odds
Calculating poker odds involves mathematics, for those who find math a little confusing (and there are many). The following brief article will help shed light on poker odds during different stages of the game. Keep in mind that these poker odds are for Texas Holdem but all games follow the same mathematical trend and so calculating the odds of winning and losing across most poker games is quite similar.
Poker odds
There are 19, 600 possible pre flop combinations and this is calculated after 2 cards are dealt. Once receiving 2 cards a player has a 1in 49 chance of any card following next and this trend continues as the player has a 1 in 48 chance of the next particular card falling. Additionally, once a player is dealt 2 cards there are 20, 118 760 possible board combinations.

There are definitely many more combinations and scenarios that can be calculated, yet all these poker odds follow the same mathematical formula. Knowing the amount of cards remaining in the deck, and the cards available to see, can significantly help you calculate the strength of a hand and perhaps determine the proper betting strategy. Of course a person will need time and practice in order to calculate the poker odds because there are always other factors to consider in a poker game!
