Is there a combination and permutation button on this calculator? I can't find it any where and really need it for my test. I'm wondering if I need to go buy a new calculator or if the button is on this one

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

It is the factorial function, used to calculate permutations and combinations in statistics.

n! = n x (n-1) x (n-2) x (n-3)... x 1

Good luck.

Let me know if you have any questions.

Combination are calculated using the nCr key. For Permutations use the nPr key.

If you have a PROB key, press it and see. Look for **nPr, **and** nCr**

Your calculator has three keys, next to which are the following markings:n! , nCr, and nPr. The one with the exclamation point is for factorials. The second is for combinations, and the third with permutations.

Syntax of the command.

If the markings are on the keys, the functions are accessed directly. If the markings are on the body of the calculator, you access the functions by pressing SHIFT and the key.

12 [!] gives 12 factorial

12 [nCr] 4 gives the combinations of 12 objects taken 4 at a time (order not important)

12 [nPr] 4 gives the permutations of 12 objects taken 4 at a time (order is important.)

There is no probability key on the 30Xa as there is on the 30XIIS. The shifted functions of the 8 and 9 keys will calculate the number of combinations and permutations, respectively. The shifted function of the 3 key will calculate the factorial. There is no random number generator.

Yes, your calculator can do them. Press the PRB key to bring up the Probability menu. Among them you'll find nPr and nCr for permutations and combinations, as well as ! for the factorial.

To compute 4C2, press 4 PRB right-arrow 2 ENTER. Permutations work the same way, only without the right-arrow.

Hello,

Use the sequence [2ndF][nPr] for permutations and [2ndF][nCr] for combinations.

Exemples: 10(nPr)3 is entered as 10[2ndF][nPr]3 [=] gives 720

5(nCr)2 is entered as 5 [2ndF][nCr] 2 [=] gives 10

Hope it helps.

You can enter combinations and permutations.

If the order of the selection matters (ie. 1st, 2nd, and 3rd place out of 40 contestants) use permutation. Enter:

40{shift}{nPr}3 and then [=] for your answer set (=59280 possible ways).

IF order doesn not matter (ie. a team of 3 from 40 possible members) then it is a combination. Do the same as above, but substitute {nCr} for {nPr}. (= 9880 possible ways).

For your question: a three-digit set, selecting from 0-9. There is no specified order, it is a combination. The total n=10 (there are 10 digits in the range 0-9) and you are selecting 3.

so.... 10[nCr]3 with give the number of possible combinations.

Hello, By examining a picture of the calculator, I could not find a key that allows you to calculate combinations, nor permutations. There is however a key to calculate factorials. You can use it to calculate permutations and combinations as follow Permutations with repetitions : nr where n is the number of things to choose from, and you choose r of them (Repetition allowed, order matters) Permutations without repetitions: (2 factorials to calculate anda division)

here n is the number of things to choose from, and you choose r of them. (No repetition, order matters) Combinations (three factorials to calculate and 2 divisions) where n is the number of things to choose from, and you choose r of them. (No repetition, order doesn't matter). As you can see, the factorial key allows you to calculate combinations and permutations. If you are on the look out for a not too expensive scientific calculator, check the new Casio Natural Display calculators (Casio FX-115ES, FX-991ES). Other potential calculators are the TI Multiview, the Sharp WriteView. Hope it helps
