How to use 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
HEY I AM USING FX911ES,
i ant to know steps for linear interpolation,
given= X Y
3.0 5800
3.2 6000
no to find value of 3.1... in my old calculator it was.
(fx911 MS) STEPS WERE.....
mode(2times)- REG- linear
3.0,5800 m+ (n1)
3.2,6000 m+ (n2)
3.1 (reg 2times) KITES sign =
now please show steps of fx911MS...
How to solve this in my fx911ES calc
attached in the picture...i want to get the value of RB
