Take mutual exclusivity into account. Sometimes, certain outcomes can overlap - the odds you calculate should reflect this. For instance, if you're playing poker and you have a nine, ten, jack, and queen of diamonds in your hand, you want your next card either to be a king or eight of any suit to make a straight , or, alternatively, any diamond to make a flush.

Let's say the dealer is dealing your next card from a standard fifty-two card deck. There are thirteen diamonds in the deck, four kings, and four eights. The thirteen diamonds already includes the king and eight of diamonds - we don't want to count them twice. Thus, the odds of being dealt a card that will give you a straight or flush are In real life, of course, if you already have cards in your hand, you're rarely being dealt cards from a complete fifty-two card deck.

Keep in mind that the number of cards in the deck decreases as cards are dealt. Also, if you're playing with other people, you'll have to guess what cards they have when you're estimating your odds. This is part of the fun of poker. Know common formats for expressing gambling odds. If you're venturing into the world of gambling, it's important to know that betting odds don't usually reflect the true mathematical "odds" of a certain event happening.

Instead, gambling odds, especially in games like horse racing and sports betting, reflect the payout that a bookmaker will give on a successful bet. To add to the confusion, the format for expressing these odds sometimes varies regionally. Here are a few non-standard ways that gambling odds are expressed: Decimal or "European format" odds. These are fairly easy to understand. Decimal odds are simply expressed as a decimal number, like 2.

This number is the ratio of the payout to the original stake. For instance, with odds of 2. Fractional or "UK format" odds. This represents the ratio of the profit not total payout from a successful bet to the stake. Moneyline or "US format" odds. These can be difficult to understand.

Remember this subtle distinction! In moneyline odds, a simple "" no plus or minus represents an even bet - whatever money you stake, you'll earn as profit if you win. Understand how gambling odds are set. The odds that bookmakers and casinos set aren't usually calculated from the mathematical probability that certain events will occur.

Rather, they're carefully set so that, in the long run, the bookie or casino will make money, regardless of any short-term outcomes! Take this into account when making your bets - remember, eventually, the house always wins. Let's look at an example. A standard roulette wheel has 38 numbers - 1 through 36, plus 0 and If you bet on one space let's say 11 , you have 1: However, the casino sets the payout odds at Notice that the payout odds are slightly lower than the odds against you winning.

If casinos weren't interested in making money, you would be paid out at However, by setting the payout odds slightly below the actual odds of you winning, the casino will gradually make money over time, even if it has to make the occasional large payout when the ball lands on Don't fall prey to common gambling fallacies. Gambling can be fun - even addictive. However, certain widely-circulated gambling strategies that at first appear to be "common sense" are, in fact, mathematically false.

If you've been at the Texas Hold 'Em table for an hour and you haven't been dealt a single good hand, you may want to stay in the game in the hopes that a winning straight or flush is "right around the corner. The cards are randomly shuffled before every deal, so if you've had ten bad hands in a row, you're just as likely to get another bad hand as you are if you've had a hundred bad hands in a row.

This extends to most other games of chance - roulette, slots, etc. Sticking with one specific bet won't increase your odds. You may know someone who has "lucky" lotto numbers - though it can be fun to bet money on numbers that have special personal meaning, in random games of chance, you're never more likely to win by betting on the same thing every time than you are by betting on a different thing every time. Lottery numbers, slots, and roulette wheels are completely random.

In roulette, for example, it's just as likely that you'll roll "9" three times in a row as it is that you'll roll any specific three numbers in order. If you're one away from the winning number, you weren't "close. You weren't even close.
