COMBIN
The COMBIN function calculates the number of combinations for a specified number of items selected from a set without regard to order. It is useful in statistics, probability, and combinatorics. Use this function to determine combinations of elements in a set.
Syntax 🔗
=COMBIN(n, k)
n | The total number of items in the set. |
k | The number of items to be chosen for each combination. |
n | The total number of items in the set. |
k | The number of items to be chosen for each combination. |
short_description | A brief description of the function. |

About COMBIN 🔗
Use the COMBIN function in Excel to calculate the number of ways you can choose a specific number of items from a larger set, without considering the order. This function is useful in statistics, probability, and combinatorial analysis. Simply provide the total number of items and the number of items to be chosen, and COMBIN will return the count of unique combinations. This helps you efficiently explore different scenarios and possibilities.
Examples 🔗
You have 10 different books on a shelf and want to choose 3 to read. Use the COMBIN function to calculate the number of combinations of books you could choose. The formula is: =COMBIN(10, 3). This will give you the total number of unique combinations of 3 books from the set of 10.
You have 8 different colors of paint and want to choose 2 to mix for a new color. Use the COMBIN function to calculate the number of combinations of 2 colors. The formula is: =COMBIN(8, 2). This will give you the total count of distinct combinations of 2 paint colors from the palette.
Notes 🔗
The COMBIN function requires that both n and k are non-negative integers. Make sure your inputs are suitable for the combinations you need to calculate.
Questions 🔗
The COMBIN function calculates the number of combinations of k items that can be selected from a set of n items.
No, the COMBIN function is specific to calculating combinations, where the order of selection is not considered. For calculating permutations, which involve the arrangement of items in a specific order, the PERMUT function should be used.
What is the maximum value thatn and k can take in the COMBIN function?The maximum values for n and k in the COMBIN function depend on the computational capabilities of Excel, but theoretically, they can be any non-negative integers. However, it's essential to consider the practical significance and computational feasibility when choosing the values for n and k.
