How do you calculate binomial CUMULATIVE distribution on the Texas 30XIIB calculator without simply adding all the individual binomial pdfs? is there a mode or an equation that can be used? thanks in advance!

Ad

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.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

New users get to try the service completely Free afterwhich it costs $6 per call and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

Goodluck!

it is just a (-) symbol and it is beside the decimal point (.) button

Hello,

Make sure you have fresh batteries. Increase contrast

First possibility.

Press [2nd] and hold pressure

Press UpArrow and repeat this step

2nd Possibility

Press [2nd] key then release

Press UpArrow then release

Repeat the two steps in sequence till contrast is to you liking.

Hope it helps.

SOURCE: Inputing scientific notation into my calculator

Hello,

1. To convert a number to scientific equation, use [2nd][Sci]

Exemples 12345 [=] screen shows 12345 Then [2nd][Sci] coverts it to 1.2345 ^04 to the power 4.

2. To enter directly a number in scientific notation (e.g. -1.2345 X10^(-65) a very small number) you use the [EE] key 1.2345[+ /-][EE][+/-]65 shows as -1.2345 -65

1.6X10^(-19) 1.6[EE][+/-]19 shows as 1.6 -19

Hope it helps

SOURCE: how to clear the memory key on Texas instrument

Hello,

Your calculator has 3 memories (M1, M2,M3)

To store the number 170 in M1 use** 170[STO]1 **

To recall a number from M1 use [RCL]1

To add a number to the content of M1 [2nd][SUM]1 (adds displayed value to contents of M1).

[2nd][EXC] 2 exchanges the value already displayed with the contents of M2:

To erase (clear) a memory register, just store 0 in it.

Hope it helps.

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

Do you have a question about the binomial probability distribution function or the binomial cumulative distribution function?

There are a lot of probability distributions: binomial, chi-square, F, normal, poisson, and t, just to name a few. Do you have a particular one in mind?

I encountered this same problem with the TI-84. Turns out you have to put your P (Percentage) as out of one hundred. For example. With my problem I had;

Trails: 13

P: 53/100

X Value: L1 (List 1)

And then it posted my probabilities to the L2 list. For some reason if you just put 53, or whatever your percentage of success in, it won't calculate.

You'll find the binomial distribution functions in the DISTR menu (press 2ND [DISTR]).

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

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

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.

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.
