SOURCE: BINOMIAL DISTRIBUTION

Hello,

Let us start with a review of the formula for the binomial distribution

**f(r;n,p)=n!/(r!(n-r)!)x(p^r)x(1-p)^(n-r) **

But **n!/(r!(n-r)!)=(nCr)** you get

f(r;n,p)= **(nCr)x(p^r)x(1-p)^(n-r) **

Exemple : n=25, r=6, p=0.7

**f(6;25,0.7)= **25** [PRB] [-->] **6 **[ x ] {**0.7**[ ^] **6 **}[ x ]{**0.3**[ ^ ]**19**}**

The arrow means a horizontal scroll once to select the (nCr) function. [ x ] stands for the multiplication sign.

[ ^] is the raise to the power key

The { } are used here as parentheses to make formula legible.

Hoe it helps

Hello,

This is for the TI-30 XIIS. It should work for you once you find the (nCr) key or the menu item under PRB key. If you know the formula skip to Exemple

Hello,

Sorry, but you information is wrong, to find the binomial distribution use the PROB menu not the STAT menu. Its name is randBi

[2nd][MATH][F2:PROB] scroll right.

Hope it helps.

Do you have the Stats/List-Editor app loaded? If not, you can download it from http://education.ti.com

You can also try StatLite, available from http://www.ticalc.org

The key is accessed by sequence [2nd] 8

Eg; Selecting 3 out of 5

5C3 is entered as 5 [2nd][8] 3 [=], result is 10

The only known equation for the cumulative binomial distribution is the sum of the individual binomial probabilities. Some more sophisticated (and more expensive) calculators have that equation built in, but the 30xii does not.

If n>30 and n*p>5 and n*(1-p)>5 then you can approximate the cumulative binomial with the normal probability function, but again the 30xii does not have that built in.

The number of combinations of **n objects taken r at a time **has a reserved symbol **nCr**. On calculators it has a special key (or shifted key) marked **nCr.**

By definition** nCr=(n!)/((r!)*(n-r)!)**=**nC(n-r)**

In what follows, I am using parentheses to enclose what is in the denominators). So

10!/(8!2!)=10C2 or 10C8 =45 (they have the same value)

10!/(9!1!)=10C9=10C1=10

10!/(10!0!)=1

The distributions do not exist on the TI 89 Titanium. But you can download an application from the education.ti.com website. It is called tistale.89x. Here is the link to it.

Yes, eleven million is rather extreme for the binomial distribution. For this large a value the binomial distribution is sufficiently indistinguishable from the normal approximation.
