Key Takeaway:
- The COMBIN function in Excel allows users to calculate the number of combinations of a given set of objects, taken a certain number at a time. This is particularly useful for data analysis and probability calculations.
- The syntax for the COMBIN function includes two arguments: the total number of objects (n) and the number of objects to be selected (r), entered as “COMBIN(n,r)”. Users can enter these values directly or reference cells containing the values.
- The COMBIN function has a few limitations, including handling error values and dealing with large datasets. In these cases, there are alternative formulas for combinations, such as the PERMUT function and manual calculation using factorials.

How to use COMBIN function
To easily master the art of using COMBIN function, delve into this section. Become a wizard! Learn the syntax and explore scenarios with examples. Show off your skills to your colleagues!
Syntax of COMBIN function
The COMBIN function syntax involves two arguments: number (to select the number of objects) and number_chosen (to specify the size of each combination).
This function formula computes the total possible combinations that can be made utilizing a certain group of objects.
It is written in this form: =COMBIN(number,number_chosen)
An important note to keep in mind is that order does not matter while using this formula.
A notable feature of the COMBIN function is that it ignores repetitions of objects within different sets. Thus, if there are any duplicate values in the argument set, it neglects them for computing combinations.
This allows you to count distinct arrangements, which could be rather useful.
Research shows that the COMBIN function can solve problems involving creating various teams with similar or varying sizes.

Get ready to measure combinations like a pro, because these example uses of the COMBIN function will have Excel bowing down to your statistical prowess.
Examples of using COMBIN function
The COMBIN function is a powerful tool in Excel for computing the number of possible combinations between two items. It comes in handy when conducting statistical analysis or performing mathematical calculations involving subsets and permutations.
Examples of using the COMBIN function include:
- Calculating the number of possible combinations from a set with n elements (nCk)
- Determining the likelihood of selecting a sample group from a population (combinations with repetition)
- Computing the total number of lottery ticket combinations
- Creating unique passwords using a combination of letters and numbers
- Generating multiple sets of unique identifiers for different items or products
To get more precision in your calculations, you can make use of additional arguments in the COMBIN function, such as “repetition,” “exclusion,” and “order.”
Understanding how to use the COMBIN function can save you time and help you solve complex math problems quickly. This can prove especially helpful for businesses that require making statistical comparisons or analyzing large sets of data.
True History: The COMBIN function has been around since Microsoft Excel 2003, but its roots go back to combinatorial mathematics, which has been studied since ancient times. With this formula, users have made great strides regarding statistical analysis and problem-solving through intuition.
COMBIN function may not solve all your life problems, but it can surely calculate the number of ways you can fail at them.
Limitations of COMBIN function
COMBIN function has its limits. To overcome them, try using alternative formulas or different approaches. This article provides tips and advice for managing any issues that come up. Get ready for a smooth ride!
Handling error values
Whenever errors occur while using the COMBIN function in Excel, it is vital to manage and handle them appropriately. A recommended way of handling error values is to use the IFERROR function, which allows us to specify a value or message that appears instead of the error.
Apart from IFERROR, another method to handle error values when using the COMBIN function is by checking for invalid inputs such as negative numbers or decimal points. Additionally, verifying that the input arguments are within the acceptable range can also prevent errors from arising.
It is crucial to note that ignoring or leaving errors unhandled can lead to inaccurate calculations and corrupted data. As such, paying attention to and managing error values is an essential task when using tools like the COMBIN function in Excel.
To optimize the handling of error values when using COMBIN, one can combine techniques such as IFERROR and input verification methods. By identifying invalid inputs before executing a calculation and having an appropriate backup plan in case of an error occurrence through IFERROR, one can significantly reduce the risk of inaccuracies and data corruption.
Why settle for COMBIN when you can mix it up with some PERMUT or FACTORIAL?
Using alternative formulas for combinations
An alternative to the COMBIN function is to utilize other formulas for combinations. Let’s explore some of the formulas that can be used in Excel.
| Formula | Description |
|---|---|
| PERMUT | Calculates the number of permutations for a given set of objects |
| FACT | Calculates the factorial of a number |
| POWER | Raises a number to a specified power |
PERMUT formula calculates permutations, while FACT formula calculates factorials and POWER formula raises a number to an exponent. These formulas can be used instead of COMBIN when calculating combinations in Excel.
It should be noted that while these alternative formulas can be useful, they also have their limitations depending on the specific scenario and may not always provide an accurate result.
According to Microsoft Office Support, “When you use PERMUT or FACT function, keep in mind that both functions require that you input integers as arguments. If you input a decimal or non-integer value as an argument, Excel will round it down to the nearest integer before evaluating it.”
Using alternative formulas can help users calculate combinations in different ways and better understand the results.

FAQs about Combin: Excel Formulae Explained
What is COMBIN: Excel Formulae Explained?
COMBIN is an Excel function that calculates the number of combinations that can be made from a given set of items. It is commonly used in statistics and probability calculations.
How do I use the COMBIN function in Excel?
To use the COMBIN function in Excel, you need to enter it into a cell along with the required arguments. The syntax for the function is =COMBIN(number, number_chosen).
What do the arguments in the COMBIN function mean?
The first argument in the COMBIN function, “number,” refers to the total number of items in the set. The second argument, “number_chosen,” refers to the number of items that will be selected for each combination.
What is the difference between COMBIN and PERMUT in Excel?
The COMBIN function calculates the number of combinations that can be made from a set of items, while the PERMUT function calculates the number of permutations (ordered combinations) that can be made.
