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**

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.

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.

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.

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.

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.

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

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.
