What are the steps for calculating combinations and permutations.

How do I input the data such as a three digit set using 0-9.

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.

I do not think you can do that with your calculator.

Combinations and permutations reffer to mathematical definitons of such.

e.g How many five card combinations are possible out of 12 card set.

nPk=n!/(n-k)! and

nCr=n!/(r!(n-r)!)

There are 252 combinations of ten items taken five at a time.

If the order matters then there are 300,240 permutations of ten items taken five at a time.

Do you want combinations or permutations? They're different things. A combination of n items taken m at a time, sometimes written "nCm", selects m items from a group of n without regard to order. A permutation of n items taken m at a time, sometimes written "nPm", selects m items from a group of m with regard to order.

Given six numbers, there are six combinations of one number, 15 combinations of two numbers, 20 combinations of three numbers, 15 combinations of four numbers, six combinations of five numbers, and one combination of six numbers.

Given six numbers, there are six permutations of one number, 30 permutations of two numbers, 120 permutations of three numbers, 360 permutations of four numbers, 720 permutations of five numbers, and 720 permutations of six numbers.

One-number combinations: { 1 2 6 9 }

Two-number combinations: { 12 16 19 26 29 69 }

Three-number combinations: { 126 129 169 269 }

Four-number combinations { 1269 }

Or did you want permutations?

Look for a key marked nCr for combinations, or one marked with nPr for permutations. The marking may be on the calculator plate. In that case you will use the Shift, 2nd or 2ndF key before.

Enter n, press the key then r.

For the factorial fuction x! or n!, you enter n then press the key. .

The symbol is used to represent the factorial function. That function appears in probability theory, so you will find it under the Prob menu.

Turn Claculator ON

If you see no icons, press the MENU key.

Press 1 to select Run/Matrix home screen.

Press the OPTN key

Press F6> to move to the next page of TABS.

The probability Menu is activated by pressing the F3 key.

The factorial function is shown at the bottom of the screen as x!

Enter the number whose factorial you want to calculate, and press F1.

The calculator cannot calculate the factorial of numbers larger than 69.

Note: If you have to calculate permutations and combinations, do not use the definition in terms of factorials. Rather, use nPr for permutations and nCr for combinations.

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.)

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.
