Probability - Tree Diagrams 1 

I have been taught this so many times over the years and I can say this FINALLY makes sense! Thank you so much

I have a test tomorrow and this made everything so clear. Thanks for the help!

Beautifully explained! An excellent teacher can literally explain a complex concept in 6 minutes, and the student doesn't have to spend hours trying to figure out what's going on. Thank you!

The best tree diagram explanation, and the simplest way to learn no confusion. Short and sweet.

Thanks for teaching me how to do the questions. You are even better than my maths teacher.

This video is 11 years ago from today and still gold 👏🏻👏🏻👏🏻. Thank you 🙏🏻

TYSM, helped me so much, trying to learn probability during corona time

I though (at first) he was a text to speech voice.

This is so helpful. Thank you so much. I won't have a problem with tree diagrams anymore thanks to you :)

Thank you. This is the first math tutorial I was able to finish watching and understand.

I can't believe I never used to understand this, it seems so simple. They should really start showing us more RU-vid clips in class, half of my teachers are really under qualified. Thank you for your help

Great straight forward explanation for a 50 year old, first time math teacher (that is me), thanks for posting

Well, that was confusing ! All I know is, it doesn't matter what colour the sweets are - they are all bad for your teeth.

i am telling you you are better than my math teacher, i am doing online classes and she makes things so complicated and when i watched this everything made sense thank youu 💘

What I did not understand in class, I got it in 6 minutes. Thanks a lot!

this was made before i was born

Thx for explaining my maths teacher is impossible to understand

Haha my maths book tried to teach me how to calculate different possibilities using tree diagrams with a bunch of confusing formulas. This made things so much easier for me! Thanks again :D

This is amazing.Some of our teachers were suppose to teach us this instead of those long formulas.this is simple and easy.

Please become my maths teacher😶

It was explained so well they should just show us videos like this in class

your last line helped allot,multiply along the branches and add up the results,thank you *13 yrs later*

thanks for saving my life 14 years later

My maths tutor has recommended to watch two videos explaining probability (I was never taught them at school) one of them being BBC Bitesize. I have watched them and a couple of others but this is by far the best explanation I have come across. I will find more videos by Ron Barrow to teach me maths, hoping they are as easy to understand as this one.

i love how people in the movies use many sound things and so much editing to make it sound like how he sounds but he just uses an old mic from 2009 and sounds exactly like how it is in the movies

thanks so much mate, got an exam tomorrow and revising my bad choices, this is really simple now thanks!!

Fantastic! Thank you so much, its exam week next week and I've been preparing for a while and I only just learnt this so thank you x

Dude, my teacher made this seem so hard..,,that tree is so helpful to visualize and organize!

this was so helpful - this is such a good explanation compared to my teacher's!

i have a test tomrrow,thank you so much,the teachers at school cant explain,thank you so much

Revision lesson, probability ain't to bad but always good to have that extra backup!

THANK YOU!!! I have a test tomorrow and this really helped❤️

wow, my teacher never told me anything about an outcome, it's made it so much easier so starting from i'll be using an outcome everytime i come across and ANNOYING tree diagram problem, THX FOR THE HELP!! :D

I love that 99% of us here have a test tomorrow.

Thanks man I completely forgot how to do this and you helped me remember it

umm writing a Maths exam and you made it seem so simple for me. God bless you

thanks man need this for a test tomorrow

This has indeed made life easier

Thanks a ton sir. .ay Allah Almighty bless you forever ameen 🙏.

i cant learn in school and from a text book but these youtube videos seriously help me out

I searched for many videos about probability but yours was the one which I understood from it easily. Like- Done. Subscribe- Done. Comment- Done.

oh my god are u serious!!! how i didnt get this for 6 lessons straight and understood it in 6 mins still remains mystery to me :O

😊Thank you so much. Now i really understand this. Just in time for my exam. You are a God sent . Thank you so much ❤❤❤.

Thank you so much, you've explained it a million times better than my teacher!

Incredibly useful and easy to understand! Thank you

Thank you! This really helped. Got a coursework with a question and have not done the topic as yet in class. Well explained.

My maths teacher gave our class a list and told us to revise them without teaching it to us!! So this really helped thanks.

Best explanation ever of Probability Trees.

Thank God for youtube math videos. My teachers only confuse me in class, then I come home and learn it on youtube, every time. :)

good presentation and script, easy to understand, well simplified

Solving a probability question using tree diagram is way better than using Bayes theorem (which can be confusing at times)

Thanks god u help me how to understand this Topic.....bless you

The first pick is replaced. There are the same balls in the bag for the second draw. If you don't replace then you have the situation that I describe in the second video Probability - Tree Diagrams 2. Take a look.

The first video I actually found useful

Thank you so much for this! you explained it better than my teacher does and i really tried to understand and i also really payed attention again when explained it a few more times but i just couldn't seem to get it...Once again, THANK YOU!

Thank You bro you helped me study for my test.

We have a math test tomorrow and this wasn’t taught to us. Thanks so much for making this clear

The Internet is better at math than my teacher

OMG this video was taken i 10 years ago and some comments were 4 or 5 or older years ago this video is helpful thank you for posting it also who's reviewing this comment in 2030 #2020Coronoavirus

When you multiply two fractions that are tenths, the answer has a denominator of 10x10 = 100. If you multiply 3/10 by 7/10 you get 21/100. If you don't get that then look again at how to multiply fractions.

thank you very much,you have completely clarified everything for me in a tree diagram.

wow tyvm sir, i have a test tomorrow and i didnt understand tree diagrams, u showing makes it easy, tyvm!

you explain things really clearly, this video really helped me i hope you can keep going.

your a life saver, i can do probability now thanks to you!!!!!!!!! i hate maths teachers because they carnt teach!!!!!!!!!, thank you :D

Thank u I have a test tommrow and this helped me alot 🙏🙏

Thank you so much, never understood tree diagrams but as i have my GSCE maths mock coming up i thought i'd better learn which i thought would take me ages. But after this video i get it!!

This video was very informative and helped me more than my professor and this video was made in 2009.

Thank You So Much i have a gcse on data handling on monday and this is the only part i did not understand i totally understand probability tree diagrams all thanks too you

I think I'm so much late 😂 but u have solved a great problem today...my all respect to you ❤️

I have a test tomorrow, I know this is late but this clearly helped me out to understand it.

So much more understanding than my teacher OMG! Thank you so much!!

I needed this to help me understand a question on a math study guide, thank you so much!

You are a life saver for sure.

I have an exam today and this helped a lot. Thank youuuuu

since 2009 and still helpful thank u so much.....

Great teaching skills mate, helped me alot

This is amazing. Your even better at explaining this than my maths teecher.

Thanks, I now have a better understanding on how to do these types of questions!

Helping me with my math project 2 weeks before the semester ends

M8 that really helped me out a lot. You explained everything so clearly and as simple as possible. Now I have a better chance getting high marks in my exam. Thank you :D

OHMYGOD. I LOVE YOU. THANK YOU SO MUCH. I wish my maths teacher explained this as well as you do! =)

Thank you Ron,you made it so much easier

very useful even in 2023

Thank you for your video-your comments about multiplying probabilities when adding/combining a result and adding P when using 'or' in answering the question cleared up my difficulties! So grateful to you

Thanks bro for showing such an easy method of solving probability using tree diagram. Very useful.

Thank you very much! it really helped! I suggest you do more math video's your really good at explaining!

Thank you, it is easy to comprehend with your videos :)

very clear good teaching

My teacher eats his tie whilst teaching, so I never understand him. This is as good as 500k!

Omg thank you so much!! This makes so much more sense!

Duuuude... thank you. I was having trouble with a question similar to this one except sweets were coins. Everything else,same. U just did my investigation for me XD

Thank you.Now tree diagrams seem so simple to me. XXXX

GCSE higher maths tomorrow, i think this video just made me able to get 2 more marks. thx a lot

Omg, thank you so much for the help. It is hard to understand my math teacher, and you just helped me so much.

THANK YOU SOO MUCH - got a test tomorrow!

why does the blue second pick not decreasing. since u pick the blue sweets? sorry hope you know what im sayin. im not very gud in english

needed to know how to do at least one, and this helped me get it, Thanks!
