Question about Texas Instruments TI-86 Calculator

# I'm using a TI-86 to solve my Binomial distribution. My teacher is teaching using a TI-83 and is telling me to use the binompdf and binomcdf feature. I can't find those. If you could please tell me where they are in my calculator I would appreciate it. Thanks.

No they're not. I have looked there for 20 mins. That answer is incorrect. 2nd Math has no section called stat. Under More there is only one subsection, INTER and I know that isn't right.

### Binompdf equals 0?

If the probability of passing the driving test is 0.8, then the probability of exactly 11 people passing the test out of 200 candidates is less than 1 in 10^100, which is zero as far as the calculator is concerned. Is this what you're trying to calculate?

If you want to know the probability that 11 or more people have passed, then you want 1-binomcdf(200,.8,10) which will give you 1 since the probability of 10 or fewer passing is zero.

Think about it. If you have a group of 200 adults, how likely is it that only 11 of them have driver's licenses?

### Binompdf binomial binomcdf

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

### Binomial Probability Distribution

I have no idea what the problem is about. When you use the key sequence [2nd][VARS] (Distr) the screen shows two tabs at the top DISTR and DRAW. By default the cursor (or highlight) is on the 1st (DISTR>1:normalPdf). Under that TAB you have 15 distributions. Where ever the cursor might be, you can always direct it to select the distribution you are interested in.

### I have a ti3 and ti 86 but not got intructions for ti86 and was considering getting ti92 but not sure if the ti 92 is any better than what i have

That depends on what you need to do with the calculator. The TI-83 is better at some things, the TI-86 is better at some other things, and the TI-92 is better at yet other things.
The 83 and the 86 both use the Z80 processor, though the 86 is quite a bit faster. The 92 uses a 68000 processor. Though the 83 has a faster processor than the 86, the 86 has some additional calculus capabilities.
There's a good comparison of present and past models here.

### What is the different between ti-86 and ti-83

The 86 has more memory. It also has some advanced calculus capabilities the 83 doesn't. However you're much more likely to see examples for the 83 in textbooks and other references.

### I totally forgot how to do binomial pdf can you help on my TI-84

Hello,
Press the yellow [2nd] key then [VARS] (DISTR) to access the distributions. Scroll Up or down to see 0:binompdf( . Press 0 |ENTER|. The command echoes on the screen as binompdf(. Complete the command by entering the number of trials, the probability of success, and the value expected. Number of trials, and the value expected are integers.
You can also run the command giving it a sequence of expected values. In that case the sequence of expected values must be enclosed in curly brackets
Hope it helps.
binompdf ( number of trials, p, { expec_value1, expec_value2, ...} ) [ENTER]

### I was told that, to do binomial distributions on a ti-86, I would need to hit 2nd Math, then More, and I should see something that says STAT and go from there to get to DIST and Binomi. I see nothing...

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.

### Error message with binopdf function

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.
