SOURCE: binomial function in calculator fx-911ES

Hello,

The binomial probability distribution is defined as

P(r;p;n) =(nCr)(p^r)*(1-p)^(n-r)

where n is the number of trials, p the probability of success, and r the expected result.

Let n=20, r=7, p=0.15 ( I do not know wether this exemple has any meaning in the context of your problem, but you have to enter values that mean something to you. I am only showing you the key strokes

To enter 20C7 you press 20 [SHIFT][nCr]7 ;

To enter 0.15 to the power 7 you type 0.15[X to ] 7 the key is between

[x²] and [log]

To enter (1-0.15) to power 20-7, you type 0.85 [X to] 13

With [*] standing for multiplication key , and [X to] the raise to power key, the exemple above can be entered as **( 20 [SHIFT][nCr] 7) [*] ( 0.15 [X to] 7 ) [*] ( 0.85 [X to] 13 ) [=]**

Here is a screen capture to show you what it looks like. However on this calculator the combination 20 [SHIFT][nCr] 7 is represented as nCr(20,7).

Hope it helps

SOURCE: Casio fx-991ES, how to calculate

At a blank screen, enter your IRR formula in terms of the variables using ALPHA and ')' for variable X. For example: -1000 200/((1 X)^1) 200/((1 X)^2) ... rest of subsequent years. Then, press CALC. It will prompt you to enter values of your variable (X in this example). Don't worry if there's already a value displayed - this is just the most recent value that has been stored as that letter. Simply enter your value (in terms of your IRR guess) and then press [=]. You will have to repeat this for each IRR guess until you reach almost ZERO.

The FX-991ES Plus barely handles simple operations on matrices of dimensions up to 3X3. It cannot find eigenvalues or eigenvectors.

In table Mode you can enter the formula for a function and generate a table of values. For a 991ES Plus you can enter two functions. However if you change MODE everything will be erased.

In EQN (equation) there is a certain number of built in formula types you can choose. You will be asked for the coefficients which will be used to solve the equation selected. However if you change MODE your lose what you entered.**So basically you cannot save formulas to use as a memory aid **(if that is what your intention is.) Sorry.

Hello,

Just in case : Press [SHIFT][CLR] (9) [3: ALL] to reset the calculator and try [MODE] again.

If that does not work, your calculator may be defective or a fake (not the genuine article). If at all possible, return it to where you bought it and get a refund.

Here is a picture of the FX-115ES, its face looks like the 991ES. Hope I am mistaken.
