### COMBIN in Excel Example #1

For any 6 objects (e.g. a, b, c, d, e, f), there are 15 different combinations of 2 objects.

These are:

And can be calculated easily by COMBIN formula in excel like as follows:

=COMBIN(6,2)

will get 15 combinations

### COMBIN in Excel Example #2

Suppose we are given ten numbers from 1 to 10 as 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10.

Now let’s use COMBIN formula in excel to calculate the number of combinations without repetitions for the other numbers of objects taken from a set of 10.

The output of the COMBIN in excel is shown in the result column.

### COMBIN in Excel Example #3

Let’s now see how we can use this function in day-to-day life. Suppose there are 20 employees and we want to pair them into two person teams. Using the COMBIN in excel, we can see the possible two person teams that can be formed from 20 employees.

Here we use COMBIN function in excel to achieve this

=COMBIN (20, 2)

the output will be 190

### COMBIN in Excel Example #4

This time consider the 5 objects as a, b, c, d, and e. And take a pair for each as shown below. Now determine the possible combinations manually and using COMBIN in excel separately as shown in the below tables.

Manual calculation on possible combinations as follows:

First make the combination with A as shown in the first column then with B as shown in column 2 and then with C as shown in column 3 and in last with D as shown in column 4 with out repetition.

Now calculate every possible combination using =COMBIN(K17,K18).

We will get 10:

### COMBIN in Excel Example #5

Combination in excel can be used as a VBA function.

Sub usefunction()

Dim dblCombin As Double // declare a variable as double

dblCombin = Application.WorksheetFunction.Combin(42 , 6) //save the combination in excel o/p in dblcombin variable

Msgbox(dblCombin) //Print the output possible combinations in Message box.

End sub

Output **“****5245786”** will be printed in the message box.

**Things to Remember about the COMBIN Function in Excel **

- Arguments that contain decimal values are truncated to integers.
- If the supplied number is nonnumeric value then COMBIN function will return the #VALUE! Error.
- If the supplied number_chosen is nonnumeric value then COMBIN function will return the #VALUE! Error.
- #NUM error – Occurs when the value or any argument is outside of its constraint.
