By Excel provides functions that help you with factorials, permutations, and combinations. In the world of statistical analysis, these can be very useful. Keep reading to find out how to use these functions. FACT FACT, which computes factorials, is surprisingly not categorized as Statistical. Instead, you’ll find it on the Math & Trig Functions menu.
It’s easy to use. Supply it with a number, and it returns the factorial. Here are the steps:. Select a cell for FACT‘s answer. From the Math & Trig Functions menu, select FACT to open its Function Arguments dialog box. In the Function Arguments dialog box, enter the appropriate value for the argument. In the Number box, type the number whose factorial you want to compute.
The answer appears in the dialog box. If you enter 5, for example, 120 appears.
Click OK to put the answer into the selected cell. PERMUT and PERMUTIONA PERMUT enables you to calculate NP r. Here’s how to use it to find 26 P 5, the number of 5-letter sequences (no repeating letters) that you can create from the 26 letters of the alphabet. In a permutation, remember, abcde is considered different from bcdae.
Follow these steps:. Select a cell for PERMUT‘s answer. From the Statistical Functions menu, select PERMUT to open its Function Arguments dialog box. In the Function Arguments dialog box, type the appropriate values for the arguments. In the Number box, enter the N in NP r. For this example, N is 26. In the Numberchosen box, enter the r in NP r.
That would be 5. With values entered for both arguments, the answer appears in the dialog box. For this example, the answer is 7893600. Click OK to put the answer into the selected cell.
PERMUTIONA does the same thing, but with repetitions allowed. Its Function Arguments dialog box looks exactly like the one for PERMUT. Its answer is equivalent to N r.
For this example, by the way, that answer is 1181376. Hum rahe na rahe kal mp3 song free download. COMBIN and COMBINA COMBIN works pretty much the same way as PERMUT.
Excel categorizes COMBIN and COMBINA as Math & Trig functions. Here’s how you use them to find 26C 5, the number of ways to construct a 5-letter sequence (no repeating letters) from the 26 letters of the alphabet. In a combination, abcde is considered equivalent to bcdae. Select a cell for COMBIN. From the Math & Trig Functions menu, select COMBIN to open its Function Arguments dialog box. In the Function Arguments dialog box, type the appropriate values for the arguments. In the Number box, enter the N in NC r.

Once again, N is 26. In the Numberchosen box, enter the r in NC r.
And again, r is 5. With values entered for both arguments, the answer appears in the dialog box. For this example, the answer is 65870.
Click OK to put the answer into the selected cell. If you allow repetitions, use COMBINA. Its Function Arguments dialog box looks just like COMBIN’s. For this example, its answer is equivalent to 30C 25 (142506).

Description Returns the number of permutations for a given number of objects that can be selected from number objects. A permutation is any set or subset of objects or events where internal order is significant. Permutations are different from combinations, for which the internal order is not significant. Use this function for lottery-style probability calculations. Syntax PERMUT(number, numberchosen) The PERMUT function syntax has the following arguments:. Number Required.
An integer that describes the number of objects. Numberchosen Required. An integer that describes the number of objects in each permutation. Remarks.
Both arguments are truncated to integers. If number or numberchosen is nonnumeric, PERMUT returns the #VALUE!. If number ≤ 0 or if numberchosen.
What is the PERMUT Function? The PERMUT Function is categorized under. The function will calculate the number of permutations of a specified number of objects from a given set of objects. In, PERMUT can be useful in calculating different possible permutations.
So, it will help in rationally evaluating situations and making the correct choices on behalf of shareholders or clients. Formula =PERMUT(number, numberchosen) The PERMUT function uses the following arguments:. Number (required argument) – It is an integer that describes the number of objects.
Numberchosen (required argument) – It is an integer that describes the number of objects in each permutation. To learn more, launch our now! How to use the PERMUT Function in Excel? As a worksheet function, the PERMUT function can be entered as part of a formula in a cell of a worksheet. To understand the uses of the function, let us consider an example: Example 1 Let’s calculate the number of permutations of six objects selected from differently sized sets: Number Chosen Result Notes 5 1 5 5 possible permutations in group 1 5 2 20 20 possible permutations in group 1 5 3 60 60 possible permutations in group 1 5 4 120 120 possible permutations in group 1 5 5 120 120 possible permutations in group 1 We used the formula below: We got the results below: The number of permutations for a given number of objects is the number of combinations in each possible order.
Note that permutations differ from combinations in that, for a permutation, the order of the objects matters, but in a combination, the order does not matter. The number of possible permutations is given by the formula: Where: k is the number of objects chosen n is the number of possible objects Few notes about the PERMUT Function:. #NUM! Error – Occurs if either:. The given number is less than 0.
The given argument numberchosen is less than 0. Error – Occurs if one or both of the given arguments is non-numeric. Arguments that contain decimal values are truncated to integers. A combination is any a group of items in any order. If the order is significant, we should use the PERMUT function. If the order is not significant, we can use the COMBIN function.

Hi, The code below was written by Myrna Larson and it does what you want but not in a single pass. Paste the lot into a general midule and then on the worksheet enter the following A1= C A2 = 2 A3= A A4=B ETC Carry on filling down from A3 as far as you need.
Now IMPORTANT select A1 and run the code. Thanx for the excellent clarification buddy! Hi, Your welcome and thanks for the feedback Also most versions of this code you will find on the web will fail with an overflow error in E2007 and E2010.
It was originally written for versions of Excel prior to E2007 and in those versions the lines (2 of them) If N Cells.Count Then GoTo DataError are fine because there are less than cells on a worksheet in those versions of Excel In E2007 and later the VB statement COUNTLARGE was added and the 2 lines in the code need to be changed as below to handle the 4 cells on those worksheets If N Cells.CountLarge Then GoTo DataError In the code I posted I simply changed those lines but to do it properly then you should do something along the lines of this pseudo code. If application.version = excel 2007 then use countlarge else use count end if If this response answers your question then please mark as answer.
