Binomial Probability with TI-84
Вставка
- Опубліковано 7 тра 2019
- This 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.

You have no idea how many videos I've watched today trying to understand my homework. She explains everything well, I'm glad I found this!
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!!!
@@keithhudson3138 Couldn't agree more. After searching through content all night, this is the video being saved for future reference.
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! 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!!
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!
You are a LIFESAVER! My stats prof didn't explain these concepts at all! So I appreciate it!
You are my HERO! I have spent a week trying to figure this out. Thank you for taking the time to help make this - make sense!
Glad it helped
Dont normally comment on vids but my God this saved my life
Thanks again Maths and Stats Help for your tutorial.
god thank you for your videos and all of them honestly saved my grade!!!!!!!!!!
Your explanations are very helpful. Thank you.
i passed my 12 grade exam thans to you love your videos !!!!!
you are a GODsent, thank you so much, you saved me from a mental breakdown
This is great explanation, you have an excellent command of the subject
thank you so much!!! you helped me on a question i’ve been struggling on and now i got it ! ❤
Saved by a train of doubt, thank you so much M&SH gonna take my test in a few hours after some more studying.
This video is amazing and helped me so much, this SAVED me on my last college test.
this was more helpful than my actual teacher and textbook thank you so much you saved my life mommy
Oh my lord did this clarify all my doubts! Like you literally went over everything and then thew in extra calculator tips and I swear, this was sooo helpful! Now IK a bunch of tips that can save time when I'm testing and at the same time Ik exactly what I need to know for my math test tomorrow! Thank You So Much!!! Glad my math teacher gave us this video to help us understand what she wanted to go over in class today!
wow this is amazing, the 1-binomcdf solution and your explanation, very good thank you
this was so helpful thank you so much
Omg this helped soooo much! Thank you thank you 🙏🏼
fascinating video Math and Stats Help. I smashed the thumbs up on your video. Continue to keep up the quality work.
Thank you!
Very well done! So clear! Thank you!
Great video! Thank you. Wish there was one more variation that has both inclusive and exclusive in it.
thank u so muchh this was so helpful
Soooo helpful, thank you
You're welcome
Thank you so much for this!! Life saver haha
This is so helpful!
THANK YOU!!!!
Exactly what I needed :) thanks
Thank you! Helped so much for my stats midterm
Omg thank you SO MUCH! This video helped me a lot!! :)
amazing!
omg yes man . This finally makes sense
Glad it finally makes sense
THANK YOU 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?
How can I do a problem that says for example, "2 or more"
Thank you very much.
thanks you help so much in understanding the process. do you have any for finding probabilities for the Normal distribution
I do have quite a few with normal distribution. If you go to my website, I have all of my videos nicely organized: mathandstatshelp.com/
great
Whenever I put 1-bionomcdf in my calculator it says error. Any help on how to fix it?
You need a new Casio cauculator
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.
Math and Stats Help thank you so much. I figured out what I was doing wrong. I was putting a 1 then pressing the negative sign button instead of the minus side button.
That will do it too. Glad you figured it out.
Is there a video like this but for poisson probability distribution & hypergeometric probability distribution?
I don't have videos at this time for those distributions.
Math and Stats Help thank you regardless. If u don’t mind but will you be making videos on those distributions anytime soon?
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.
Math and Stats Help Well, I’m glad I found your channel. Your videos seem to be teaching more than what my textbook and professor combined are teaching me. Thank you again
I love you, saved my ass
I have a question so for the “between (inclusive)” one is the answer a whole number or a decimal?
It should be a decimal, but you can also write it as a percent.
@@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?
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.
@@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?
Or do I keep it as .4019 ?
how to get the calculetor??? give the link :( #MathandStatsHelp
I got mine, because I teach and it's the instructors software. I know TI sells a student edition.
You helped me out so much with this because Mystatlab didn't show me any of this it just said "use technology to figure this out"...stupid. But I'm subscribing just in case I need any help the rest of this semester cuz this was a life saver.
I'm glad it helped you.
THANK YOU!
