Binomial Probability with TI-84
Рет қаралды 63,867
5 жыл бұрынThis video demonstrates how to use the binompdf and binomcdf features of the TI-84 graphing calculator. The calculator can save a lot of time over using the formula. I demonstrate probabilities for exactly, less than, greater than, at least, at most, and in between both inclusive and exclusive.

THANK YOU! You make the calculator function so easy to understand! I was working on this "at least" problem for like 3 hours and none of the other videos made sense to me. CHEERS!!

Who are you telling? LOL!!! Seek and ye shall find. I searched high and low trying to find the right video to explain the complement. How and when to use it, and specifically how to use it on the TI-84. When she said bionomcdf used whenever it does not say exactly, that's all she wrote. THANK YOU!!!

This is absolutely a must video for everyone taking statistics. My professor allows us to use a calculator but would rather have us do this all by hand with the formula. I have a test this upcoming Wednesday and now I am confident with some practice that I will not miss any questions relating to binomials!!

Thank you so much for this, all the videos I've watched before find values for x=n or x is less than/ more than n. This whole time I was looking for how to find a the values in between two numbers like the last two examples in your videos. Thank you again, helped me so much!

Suppose we had to find the number of trials? For example, if 10% of flaked objects at an archaeological dig were arrow heads. How many flaked objects need to be found to be 90% sure that at least one is a finished arrowhead? "How many flaked objects" constitutes the unknown number of trials. Is there a way to reverse calculate in the TI-84?

Unfortunately, not for a while. Right now with moving all of the classes I teach to online, my focus right now is creating videos for the content that I have to teach. I will in the future, but right now my priority is the students I teach.

I have a question so for the “between (inclusive)” one is the answer a whole number or a decimal?
@MathandStatsHelp 3 жыл бұрын
It should be a decimal, but you can also write it as a percent.
@chloetheedoll494 3 жыл бұрын
@@MathandStatsHelp you’re the best!!! Also for the “at least” is that rounded number the answer? Example my answer came out to be .4019 so do I put the answer as 40.20 as a percentage?
@MathandStatsHelp 3 жыл бұрын
It depends on what decimal place you are asked to round to, and what number is behind the 19. If the value after the 19 is 0-4, it would stay 19. If the value is 5-9, you would round to 20.
@chloetheedoll494 3 жыл бұрын
@@MathandStatsHelp it’s a 2 so the number is 0.4019242388. I have to round up just like how u did in the video. So it would stay .4019 but for the percentage would it be 40.19?

n and x both have to be whole numbers and p has to be in decimal form not entered as a percent. Those are the mistakes that my students often make that lead to an error.
