The concept of odds concerns the idea of probability. They are the form of a proportion of several favourable results versus unfavourable ones in a given situation. They are usually formulated as a ratio (1 : 3 or 1/3).
It’s an essential element of strategy in many games of chance, such as roulette, horse racing, and poker. Whether you are an experienced gambler or just curious, that can make gambling a much more fun and profitable activity.

Step 1. Find the number of favourable outcomes in the situation
Suppose we are going to bet on the roll. In this case, we bet on the number we think will land on. Let’s bet on rolling a one or a two. In this case, there are 2 possibilities for us to win. Therefore, there are two results which we need for winning.
Step 2. Count the number of unfavourable results
In gambling, there is a mandatory chance of losing. That means we lose if we roll a three, a four, a five, or a six. Since we can lose by rolling any of those 4 numbers, there are 4 unfavourable events.
We also may look at it as the total quantity of possible results minus the quantity of favourable results.
When rolling a dice, the total amount of results equals six, one for each side of the dice. Here, we subtract two (the number of favourable results) from six. 6 – 2 = 4, i.e. we have 4 results when we lose, so we don’t want to get them.
Step 3. Write them numerically
Generally, odds are formulated as the proportion of favourable to unfavourable results, usually using a colon.
In our example, the numbers expressing success is 2 : 4,. That means 2 chances of a win vs 4 chances of a lose. If we divide both terms by the common multiple of two, it can be simplified as an average fraction to 1 : 2. Or, we can write it as an “odds ratio of 1 to 2”.
Also, we can form it as a fraction. Then, the balance is expressed as 2/4 and simplified as 1/2.
Note: A odds of 1/2 does not mean that we have half (50%) chance of winning. Nevertheless, the probability of success equals 33.3% (1/3). Note that odds are the proportion of favourable to unfavourable results, not a numerical measure of how likely we are to win.
Step 4. Learn how to count odds against
The odds 1 : 2 express favour of success. If we want to find the numbers that represent our chances of an unfavourable outcome, we need to find the odds against them.
To find them against, reverse the ratio in favour. 1 : 2 becomes 2 : 1
If you express them as a fraction, you get 2/1. Remember, as stated above, this is not an expression of your chances of losing; it is the ratio of unfavourable against favourable outcomes.
If it were an expression of your odds of losing, you would have a 200% chance of losing, which is impossible. The following is how you understand the outcome against. In reality, you have a 66% chance of losing; 2 chances of losing versus 1 chance of winning means 2 losses / 3 possible results = 0.66 = 66%.
Step 5. Know how odds differ from probability
The concepts of odds and probability are related, but they are not the same. The latter is a representation of the likelihood of a specific outcome . It is found by dividing the number of desired results by possible results.
For instance, the probability that we’ll roll a 1 or a 2 (on a six-sided dice) is 2 / 6 = 1 / 3 = 0.33 = 33%. So our odds of 1 : 2 come to a probability of winning 33%.
To find odds from a probability, we make this:
- Formulate the probability like that: 5/13 in our an example.
- Subtract the numerator (5) from the denominator (13) : 13 – 5 = 8.
- The 8 is the number of results needed for a win.
- Then, odds can be expressed as 5 : 8, proportion of favourable and unfavourable events .
To find the probability given a share:
- First, express the share as a fraction (we will use 9 / 21 as an example).
- Add the numerator (9) to the denominator (21): 9 + 21 = 30.
- The answer is the total amount of possible results.
- The probability can be expressed as 9/30 = 3/10 = 30%, the quantity of favourable ways over the total amount of possible results.
- A simple way for calculating odds with a ratio of 9/30 = 3/10 = 30%.
A simple formula for chances with a probability is C = P / (1 – P). A simple formula for calculating with a quota is P = C / (C + 1).
Tips on betting in games
Don’t fall prey to common gambling fallacies. Gambling can be fun, even addictive. However, specific betting strategies that appear to be “common sense” are, from a mathematical point of view, completely false.
Here are a few things to keep in mind when betting:
- Never expect a hot streak. Unfortunately, the odds don’t change with the amount of time you’ve been betting.
- Sticking to a specific bet does not increase chances. Lottery numbers, slot machines, and roulette numbers are entirely random.
- If you came very close to hitting the winning number, you were not “close” to winning. If you picked the number 41 for a lottery and the winning number is 42, it’s a little hard to take, but don’t be discouraged! You weren’t even close. Two close numbers (like 41 and 42) are not mathematically linked in any way in games of chance.
We advise you to check the rules of the selected game for more info. You can find charts where the odds have already been calculated on the internet. Look for free web services that calculate in real-time to guide you in games.
