The “Mathy” Way
When the order of items matters, that’s called a Permutation.
When the order of items doesn’t matter, that’s called a Combination. Since we are not allowed to repeat items, we use the following formula:
Number of possible Permutations
=
n^{r}
=
^{}
=
Number of possible Permutations
=
n!(n – r)!
=
!( – )!
=
Number of possible Combinations
=
(n + r – 1)!r!(n – 1)!
=
( + – 1)!!( – 1)!
=
Number of possible Combinations
=
n!r!(n – r)!
=
!!( – )!
=
The Visual Way
A form of the permutation problem that students commonly see is the “committee” problem. For example:
If there are 5 people, Jim, Jane, Bob, Susan, and Ralph, and only 3 of them can be on the new PTA committee, how many different combinations are possible?
In this example, there are 5 people to choose from (so n equals 5), and we need to choose 3 of them (so r equals 3).
Order doesn’t matter: if Jim is on the committee, he’s on the committee whether he’s picked first or last. Repetition isn’t allowed because Susan can’t be on the committee twice (even if she really wants to be!)
So, if we use the “mathy” way from above, we know the formula is:
Number of possible Combinations
=
n!r!(n – r)!
And we input the number 5 for n, and 3 for r, and so we know that there 10 possible combinations. But what does that actually mean?

I am interested in how many choices a person would have to divide 36 months among 3 people?
Thanks!
Andale
Hi, Frank,
I’m not sure I understand your question completely but it might be the fundamental counting principle could help. 36 events (months), 3 ways to order each month so that’s 3^36.
If you can clarify a bit and post on our forum, one of our mods will be happy to help!

Here is the problem.
A person has 36 months to divide among 3 people.
How many different combinations could there be.
For example one combo would be 12 months each.
I like the calculator, however, my problem would need a slightly different formula that I haven’t found.
PROBLEM: I have 25 choices, and want to know the total number of combinations possible. Since I want combinations, not permutations, order does not matter. To keep it simple, repetition is not allowed. The combinations can be of any number of choices (r=1,2,3,…25). I can use the calculator and solve sequentially for r=1, r=2, r=3, etc., then sum the answers. However, there should be an equation that would solve the problem in one calculation. Can you show me that equation?
Thank you,
Art
Andale
Well, Art. The calculator uses the combinations formula (n!/(n-k!)k!). As you want to know k for all possible choices (1 to 25). I don’t know of a single equation other than a summation equation (Σ (n!/(n-k!)k! from n=1 to n=25)) I would suggest Excel. Copy the formula to 25 cells and then use autosum.
Art
OK, thanks. I appreciate the quick reply, and will probably use the spreadsheet method you suggested.

So if i have a 4-input combination lock that requires pink, green or purple as the input options. How many combinations are possible and can you list them? The order doesnt matter and they can be repeated. It would be really amazing if i could get this lock open! Ive been trying with no luck all weekend. Thanks in advance!
Ok so i have a lock that i need the combo to, i had it in third grade and the numbers are only 1-9 with the usual, only three in the combination. I need all the possible combos w/ repeating numbers hoping i can see the combo and remember and if not go through all the numbers manually.

This calculator works great because its assuming each N has the EXACT same number of R. What if some N have R=4 and some N have R=5?

In that case the combinations formula itself would chance, so you’d have to do two computations (the calculator is based on the combinations formula).

Hi, Eric,
This needs the fundamental counting principle. You have 5 possible numbers, and each space on the lock has 5 possibilities so the answer is 5^5 (25) different ways.

I have seven people to be on an out of hours duty roster. It needs to change every week on a repeating cycle. I need two people at any one time out of the pool of seven to be on call per week.

(a) How many different code words can you form?
(b) What is the probability that a letter or a number is repeated?
(c) What is the probability that no number is repeated?

Hi, Jacq,
You can use the calculator to answer (a).
For b and c, use the combinations generator (scroll down). Find your outputs and from there you should be able to figure out the probabilities.
Rose
I am looking for all of the possible 5 and also 6 letter words that can come from the letters, C, C, H, O, R, U, S.
They may be in ANY order. This would have all words beginning with C through S. The calculator only shows words beginning with the 1st C. Since there are 2 C’s, then a word may contain 2 C’s, but not all words will have 2 C’s.
How can I find the correct word combinations?
Andale
Rose, I typed in C,C,H,O,R,U,S into the generator at the bottom and it did come up with a list that included two CCs. That said, it isn’t going to give you words — the letters will still be scrambled.
C, C, H, O, R
C, C, H, O, U
C, C, H, O, S
C, C, H, R, U
C, C, H, R, S
C, C, H, U, S

Rose
That is okay, since you can use any of the set letters to make a word. The letters may be in any order.
When using the letters C,C,H,O,R,U,S, they may be as such:
CHORUS
OCCURS
There is nothing saying the letters must be in the same order.
Thank you for your help.

Hi,
I’ve tried playing around with the calculator to do this but couldn’t work out how to get the two subsets in the answer.
I have nine students that I need to divide into two groups (one of four and one of five). I’d like to see all the possible grouping combinations.
The names are JackT, JackA, Tess, Carla, Will, Sienna, Lorenzo, Tom, Sam
Thank you so much for your help!
Therese :o)
Andale
What if you choose four from the nine using the generator)? The remainder will give you the five group. For example (JackT, JackA, Tess, Carla), leaves Will, Sienna, Lorenzo, Tom, Sam.

I want to add 6 numbers together to equal 45 or less – I’d like to know how many combinations if the 6 numbers I’m adding together are between 1 and 15.

They may be in ANY order. This would have all words beginning with C through S. The calculator only shows words beginning with the 1st C. Since there are 2 C’s, then a word may contain 2 C’s, but not all words will have 2 C’s.
How can I find the correct word combinations?
Rose, I typed in C,C,H,O,R,U,S into the generator at the bottom and it did come up with a list that included two CCs. That said, it isn’t going to give you words — the letters will still be scrambled.
C, C, H, O, R
C, C, H, O, U
C, C, H, O, S
C, C, H, R, U
C, C, H, R, S
C, C, H, U, S
C, C, O, R, U
C, C, O, R, S
C, C, O, U, S
C, C, R, U, S
C, H, O, R, U
C, H, O, R, S
C, H, O, U, S
C, H, R, U, S
C, O, R, U, S
C, H, O, R, U
C, H, O, R, S
C, H, O, U, S
C, H, R, U, S
C, O, R, U, S
H, O, R, U, S
That is okay, since you can use any of the set letters to make a word. The letters may be in any order.
When using the letters C,C,H,O,R,U,S, they may be as such:
CHORUS
OCCURS
There is nothing saying the letters must be in the same order.
Thank you for your help.
Hi,
I’ve tried playing around with the calculator to do this but couldn’t work out how to get the two subsets in the answer.
I have nine students that I need to divide into two groups (one of four and one of five). I’d like to see all the possible grouping combinations.
The names are JackT, JackA, Tess, Carla, Will, Sienna, Lorenzo, Tom, Sam
Thank you so much for your help!
Therese :o)
What if you choose four from the nine using the generator)? The remainder will give you the five group. For example (JackT, JackA, Tess, Carla), leaves Will, Sienna, Lorenzo, Tom, Sam.
I need to know how to get possible out come from 13 number using 3 letters
How many possible combinations are there in a bet involving 13 football games with each game having a possible outcome of win, draw, or lose?
Trying to work this out…
I want to add 6 numbers together to equal 45 or less – I’d like to know how many combinations if the 6 numbers I’m adding together are between 1 and 15. I guess order doesn’t matter as long as the outcome is 45 or less. The last thing is no more than 2 of the 6 numbers can be repeated repeated in the one equation.
I have combo lock need 4 digit number anything from 0-9 numbers can repeat no specific order and also 4 digit combo with dates 1370 4013 2363 8013
