Question about Texas Instruments TI-36 X Solar Calculator

# Permutation How do I use the Permutation button. Suppose I have 10!/(10-3)! How do I key it into the calculator to get 720?

Posted by on

You have to enter the 10, as the n factor, then press the x<>y key, then enter 3 as your r factor, then press 2nd and then nPr, and there is your answer

### How do I find the permutations button on a Casio Computer FX-CG10 Graphing Calculator

Turn calculator ON.
If you see no icons, press the Menu key then [1] to select Run/Mat.
In Run/Mat press the OPTN key, then the F6 key to pan other tabs.
Above the F3 key you see the PROB tab. Activate it by pressing F3. The permutation Tab is above F2.
To use permutations, enter the larger number (n), press F2 [nPr] followed by the smaller number.

### How do i calculate a P value

By P value, do you mean permutation, or do you mean the statistics p value?
To find the permutation P value simply type in the n (or total number of observations) then press 2nd F (the orange button) and then enter the number of spaces available and press equal.

### How can I get a numerical answer for factorials on casio fx83gt plus

Well, the calculator has a limited display screen. If a result exceeds the display capabilities of the calculator it is displayed in scientific notation. If the number is larger than 69 the calculator is not able to calculate its factorial.
If you are using some of the combination and permutation functions it is better to use the keys dedicated to them nPr, and nCr.

### When I go to use the 'log' button on TI 30XA I do not come up with the same answer as in my course book (for the examples) No real instructions on logs in the little instruction book. Have tried...

You calculate the pH with the relation
pH=-log(c) where c is the value of concentration in mol/L.
ex: c[H+]= 3.57x10^(-6)
pH: (-) [LOG] 3.57 [2nd][EE] [(-)] 6 [ ) ]
Here you have 2 change sign key press [(-)]

If you have the pH, and want to calculate the concentration that yields that value of the pH you proceed as follows
c= 10^(-pH)
Ex pH=8.23
c: [2nd][LOG] [(-) 8.23 [)]

General shortcut.
If concentration is of the form c[H+]= 1*10^(-a) where a is an integer between 0 and 14, the pH is equal to the positive value of exponent.

Ex:c[H+]=1x10^(-5) Mol/L then the pH is just the positive value of the exponent, ie 5 because pH=-log(1.x10^-5) =- log1 -log(10^-5)=0 -(-5)=5
Above I use the rule log(axb)=log(a)+log(b) , the rule log(a^b) = b*log(a)and the facts that log(1)=0 and log(10)=1, the last being true if log stands for log in base 10.

### How do I do a permutation? (npr)

Hello,
The syntax is not as you thought.
Ex: 8(nPr)3 is entered as follows
8 [X <--> Y] 3 [2nd] [nPr] [=]

The [ X <--> Y] is the exchange X and Y key.

Hope it helps.

### How do i calculate permutation in fx-82ms casio calculator

Hello,

Find on the calculator the [nPr] key either (you may have to use the [2nd] or [2ndF] key) then
1. Enter the number that corresponds to n eg. 18
2. Press the [nPr] key
3. Enter the number that corresponds to r eg. 5

18[nPr]5 gives 1028160

If you calculate combinaitions use [nCr] key.

Hope it helps

### I want to calculate permutation and combination.

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.
