There are 10,000 possible combinations of four digits when not a single combination is repeated. If the thousands place cannot be zero in a four-digit number, the smallest number will be 1000, and the biggest number will be 9999, which will be 9000 total combinations.
How do you calculate all the possible combinations?
Method 1 Method 1 of 2: Calculating Combinations Without Repetition Download Article
- Consider an example problem where order does not matter and repetition is not allowed. In this kind of problem, you won't use the same item more than once.
- n C r = n! ( n − r)! r! ...
- n C r = 10! ( 10 − 6)! 6! ...
- Solve the equation to find the number of combinations. You can do this either by hand or with a calculator.
How do you find the number of possible combinations?
How do you calculate all the possible combinations? Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the formula nCr = n! / r! * (n – r)!, where n represents the total number of items, and r represents the number of items being chosen at a time.
How many combinations can be made with four numbers?

How many digits are in a pick 4?
In any Pick 4 game, there are 4 digit positions, with each position containing a digit from 0 to 9. If one were to list all of the possible combinations of digits in each of the three positions, there would be a total of 10,000 different number combinations. Each of these 10,000 possibilities is called a straight combination. Thus, if you were to place one straight Pick 4 wager, your odds of winning would be 1 in 10,000.
How many odds of winning a single box combination?
Single (24-way): Each of the four positions has a different digit. For example, 1234. Each combination of this type has 24 different box combinations, so your odds of winning by playing one "single" box combination would be approximately 1 in 417.
How many times are quads presented?
The quads are only presented once, since they are all unique to start with.
How many ways are there in a double pair?
Double Pair (6-way): Two different digits are used twice. For example, 1122. Each combination of this type has 6 different box combinations, so your odds of winning by playing one "double pair" box combination would be approximately 1 in 1,667.
What is the odds of winning a triple 4 way?
Triple (4-way): Three of the four positions have the same digit, and the fourth digit is different. For example, 1112. Each combination of this type has 4 different box combinations, so your odds of winning by playing one "triple" box combination would be 1 in 2,500.
What is the odds of winning a quad?
Quad: Each of the four positions has the same digit. For example, 1111. Because each quad is unique, your odds of winning by playing one "quad" combination would be 1 in 10,000 — the same odds as playing a straight. (A quad is also known as a straight, in fact.)
What is a combination?
A combination is a way to select a part of a collection, or a set of things in which the order does not matter and it is exactly these cases in which our combination calculator can help you. For example, if you want a new laptop, a new smartphone and a new suit, but you can only afford two of them, there are three possible combinations to choose from: laptop + smartphone, smartphone + suit, and laptop + suit. The order in which you combine them doesn't matter, as you will buy the two you selected anyways. Combinations come up a lot when you need to estimate the number of possible connections or groupings between things or people.
How many combinations are there in the Powerball lottery?
For example, the odds of winning the US Powerball lottery jackpot are about 1 in 292 million (1/292,201,338) where 292,201,338 is total number of possible combinations. The order in most lottery draws does not matter. If we examine the poker example further: a poker hand can be described as a 5-combination of cards from a 52-card deck. The 5 cards of the hand are all distinct, and the order of cards in the hand does not matter so it is a combinatorial problem. Using our combination calculator, you can calculate that there are 2,598,960 such combinations possible, therefore the chance of drawing a particular hand is 1 / 2,598,960.
What is the difference between permutations and combinations?
The difference between combinations and permutationsis is that while when counting combinations we do not care about the order of the things we combine with permutations the order matters. Permuations are for ordered lists, while combinations are for unordered groups. For example, if you are thinking of the number of combinations that open a safe or a briefcase, then these are in fact, permutations, since changing the order of the numbers or letters would result in an invalid code. If, however, you are thinking of the number of ways to combine your dresses with your shoes or your ties with your suits, then order doesn't matter, since the end result of choosing the tie first and the suit second is the same as choosing the suit first and the tie second.

Is a lock combination a permutation?
For example, a lock combination is in fact a permuation. In another example - if you want to estimate how many computing hours you need to brute force a hashed password you calculate the number of permutations, not the number of combinations.
What is combination in math?
The combination definition says that it is the number of ways in which you can choose r elements out of a set containing n distinct objects (that's why such problems are often called "n choose r" problems). The order in which you choose the elements is not essential as opposed to the permutation (you can find an extensive explanation of that problem in the permutation and combination section).
How many combinations are there in ncr?
You can check the result with our nCr calculator. It will list all possible combinations, too! However, be aware that 792 different combinations are already quite a lot to show. To avoid a situation where there are too many generated combinations, we limited this combination generator to a specific, maximum number of combinations (2000 by default). You can change it in the advanced mode whenever you want.
How to turn a permutation into a combination?
If you already have a permutation and want to turn it into a combination, you need to remove order, i.e., regard all possible reorderings as the same object. Hence, the number of combinations of r items chosen from n items is equal to the number of permutations of r items chosen from n items divided by the number of orderings of these r items, i.e., by r!.
What is the act of rearrangement of all the members of a set into some sequence or order?
By definition, a permutation is the act of rearrangement of all the members of a set into some sequence or order. However, in literature, we often generalize this concept, and we resign from the requirement of using all the elements in a given set. That's what makes permutation and combination so similar.
What order do we arrange items in permutation?
In permutation the order matters, we arrange items in sequential order.
How many ways of arranging a word with 7 letters?
If the word has seven distinct letters, you have 7! = 5040 ways of arranging them (simple permutations of seven items). However, if some letters appear more than once, the number of arrangements gets reduced! For instance:
What is linear combination?
A linear combination is the result of taking a set of terms and multiplying each term by a constant and adding the results. It is frequently used in wave physics to predict diffraction grating equation or even in quantum physics because of the de Broglie equation. Here, you can see some common examples of linear combination:
What is a four digit combination?
Many people use four-digit combinations that are either repetitive or in sequential order. For example, 1234 is a very common choice, and other people combine the same number over and over, such as 1111 or 2222. Don't let your knowledge of the binomial coefficient go to waste.

Why do people have 10,000 pins?
Banks don’t help the problem either. Oftentimes, people have 10,000 choices when it comes to PINs because many banks will allow for repeating numbers. If your bank is a little more security savvy, you'll only have 5,040 combinations to choose from. Many people use four-digit combinations that are either repetitive or in sequential order. For example, 1234 is a very common choice, and other people combine the same number over and over, such as 1111 or 2222.
How to find the number of combinations?
Number of Combinations Formula. Finding the number of combinations that can be made with four numbers can be found through a simple equation.
