[cassandracollege]

Love it! The speaker reminds me of the depressed robot off the movie"Hitch Hiker's guide to the galaxy"..lol

[zvichaita]

awesome, thanks

[rfbarrow]

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.

[TheDroidSector101]

The second pick is wrong. Wouldn't it become 6/9 because we already picked blue leaving 6 other blues and a total of 9

[TheDroidSector101]

@TheDroidSector101 Never mind :p I just read the question again, she replaces it

[shadow36057]

[singer1711]

I frickin love you :L I learnt more in 6 minutes than 6 months! lol

[PrayingEagle]

Thank you very much, friend. It's somewhat irritating to see that I've been doing this for the past 6 months in a somewhat slower, more tedious fashion than what's been shown to me in this video. So thank you, but also damn you for not showing this to me sooner :)

[xxfaith0chickxx]

[samioa]

@rfbarrow

Very great job man! I wish there were more people like you! It took about 35 minutes for my teacher to explain a Tree diagram but I still did not understand anything!!

However this video which is about 6 minutes taught me everything about it! Now i'm prepared for the test we have tomorrow.

I just wanna thank you for sharing your knowledge to us and too keep up your good work! You deserve allot more subscribers than other people in YouTube

[MS119931]

Thank you so much! My teacher's too busy to give us a 6min. lecture! GOD BLESS YOU <3

[mrnarason]

[ilko43211]

[Coolasion]

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

[bigburst]

great job!, i really understood the material, im n college and the lecture class is taught by a grad student who has no idea how to teach, i am completely lost..this is the first tutorial i watched tonigt, and i have many left to go, b/c the test is tommorrow and i cannot fail.. 6 min of info understood, wen he taught it for a whole hour and i almost went brain dead

[SuperSoundBreaker]

I don't get it

[09littlebabe]

[ArGyProductions]

[thewiseguy48]

[MarkARecio]

Well calculated, this has helped me in preparing for the GRE Test.

[momedd767]

I have this probability question that I need you to help me solve:

Customers at a video store are allowed to rent one ,two or three movies.Use a tree diagram to list the sample space for the number of movies rented by three customers(assuming that each one rents at least one movie.)

Thank you.

[WarpTenth]

[simirkhan]

[jossh999]

this is so helpful

[hopecoyne]

very much helpful, thank you! :)

[Cyclops4770]

i do not understand why my teacher done on the 1st pick like 7/9 and 2/9 ad then on the second pick he changed the denominator to 5/8 and 3/8 maybe one had to be chucked out i dunno

[rfbarrow]

@Cyclops4770

Hi take a look ot Probability - Tree diagrams 2. The first video is about putting the sweets back each tim. The second is about not replacing. That's what makes the difference.

[adityans]

THnx

it was really helpful...

[HeartMessager]

I have looked through three books and I could not understand this... I have felt very frustrated throughout most of the day regarding not grasping a question in my numeracy booklet.

Your video is so clear and straight forward to follow - I now grasp the question i was struggling to answer. Thank you for taking the time to create these series of videos you offer, they are extremely helpful!

[redrose11123]

Thank you :)

[mathsdepartmentbhtc]

[Alz2ny]

thank you this really helped me! ;)

[mmsn11]

oh i see thx alot then xD its quite simple

[mmsn11]

it is its too long and i cnt explain and dats not how my maths teacher done it so i dunno :S im cunfused atm coz i got a exam on monday on Data handling on the second pick it souldnt be 7/10 and 3/10 it sould be 6/9 and 3/9 because if you pick a blue ball there are 9 balls left in the bag and 6 blue balls now therefore it has to be 6/9 and 3/9 but for red it has to be 7/9 and 2/9 :S if you get what i mean :)

[rfbarrow]

Look at the question. It says the ball is replaced after the first pick, so there are the same balls for the second pick. What you're talking about is when the first ball is not replaced.

In a few minutes I'll upload a video with the same question but with replacement. It will be called Probability Tree diagrams 2. Let me know what you think.

[mmsn11]

i think youv done it wrong in the second pick ?

[rfbarrow]

No, it's not wrong. Why do you think it is?

[mmsn11]

havnt you done it wrong ? please reply back i need alot of help pleasee reply back sum1
