We'll show you how to calculate combinations, and what the linear combination and combination probability are. Finally, we will talk about the relation between permutation and combination. Briefly, permutation takes into account the order of the members and combination does not.

You can find more information below! Have you ever wondered what your chances are of winning the main prize in a lottery? How probable is winning the second prize? To answer both and similar questions, you need to use combinations. We've got a special tool dedicated to that kind of problem. Our lottery calculator doesn't only estimate combination probability of winning any lottery game, but also provides a lottery formula. Try it! You'll find out how big or small those numbers are, in fact.

You might also be interested in a convenient way for writing down very long numbers called scientific notation. For example, ,,, you can write as 1. Isn't it simpler? For more information check the scientific notation rules. 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.

Seeking for every combination of a set of objects is a purely mathematical problem. You probably have been already taught, say, how to find the greatest common factor GCF or how to find the least common multiple LCM. Well, a combination is an entirely different story. Let's see how complicated it might be. Imagine a bag filled with twelve balls, where each one is a different color.

You pick five balls at random. How many distinct sets of balls can you get? Or, in other words, how many different combinations can you get? Mathematicians provide the exact solution for many various problems, e. Is there a similar approach in estimating the number of combinations in the above example with balls?

Luckily, you don't have to write down all of the possible sets! How to calculate the combinations, then? You can use the following combination formula that will allow you to determine the number of combinations in no time:. The exclamation mark! represents a factorial. Check out our factorial calculator for more information on this topic. The expression on the right-hand side is also known as the binomial coefficient.

We also use it in our other statistical calculator, called the binomial distribution calculator. If you visit this site, you'll find some similarities in the computations - for example, that binomial calculator uses our nCr calculator. Let's apply this equation to our problem with colorful balls.

We need to determine how many different combinations are there:. You can check the result with our nCr calculator. It will list all possible combinations , too! However, be aware that 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 by default. You can change it in the advanced mode whenever you want. You may notice that, according to the combinations formula, the number of combinations for choosing only one element is simply n. On the other hand, if you have to select all the elements, there is only one way to do it. Let's check this combination property with our example.

Every letter displayed in the nCr calculator represents a distinct color of a ball, e. Try it by yourself with the n choose r calculator! By this point, you probably know everything you should know about combinations and the combination formula. If you still don't have enough, in the next sections, we write more about the differences between permutation and combination that are often erroneously considered the same thing , combination probability, and linear combination.

Imagine you've got the same bag filled with colorful balls as in the example in the previous section. Again, you pick five balls at random, but this time, the order is important - it does matter whether you pick the red ball as first or third.

Let's take a more straightforward example where you choose three balls called R red , B blue , G green. There are six permutations of this set the order of letters determines the order of the selected balls : RBG, RGB, BRG, BGR, GRB, GBR, and the combination definition says that there is only one combination!

This is the crucial difference. 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.

This meaning of permutation determines the number of ways in which you can choose and arrange r elements out of a set containing n distinct objects. This is called r-permutations of n sometimes called variations. The permutation formula is as below:. Doesn't this equation look familiar to the combination formula? In fact, if you know the number of combinations, you can easily calculate the number of permutations:.

If you switch on the advanced mode of this combination calculator, you will be able to find the number of permutations. You may wonder when you should use permutation instead of a combination.

Well, it depends on whether you need to take order into account or not. For example, let's say that you have a deck of nine cards with digits from 1 to 9.

You draw three random cards and line them up on the table, creating a three-digit number, e. How many distinct numbers can you create?

The number of combinations is always smaller than the number of permutations. This time, it is six times smaller if you multiply 84 by 3! It arises from the fact that every three cards you choose can be rearranged in six different ways, just like in the previous example with three color balls.

Both combination and permutation are essential in many fields of learning. You can find them in physics , statistics, finances, and of course, math. We also have other handy tools that could be used in these areas. Try this log calculator that quickly estimate logarithm with any base you want and the significant figures calculator that tells you what are significant figures and explains the rules of significant figures. It is fundamental knowledge for every person that has a scientific soul.

To complete our considerations about permutation and combination, we have to introduce a similar selection, but this time with allowed repetitions. It means that every time after you pick an element from the set of n distinct objects, you put it back to that set.

In the example with the colorful balls, you take one ball from the bag, remember which one you drew, and put it back to the bag. Analogically, in the second example with cards, you select one card, write down the number on that card, and put it back to the deck. In that way, you can have, e. You probably guess that both formulas will get much complicated. Still, it's not as sophisticated as calculating the alcohol content of your homebrew beer which, by the way, you can do with our ABV calculator.

In fact, in the case of permutation, the equation gets even more straightforward. The formula for combination with repetition is as follows:. In the picture below, we present a summary of the differences between four types of selection of an object: combination, combination with repetition, permutation, and permutation with repetition.

It's an example in which you have four balls of various colors, and you choose three of them. In the case of selections with repetition, you can pick one of the balls several times. If you want to try with the permutations, be careful, there'll be thousands of different sets!
