CCSS Math - Probability Example 3 (Tree Diagram)

[@kutiabuna6335]

Thank you sir. I am doing my exams tomorrow and this video has been helpful.

[@queenspring6088]

❤love from Africa you explain so detailed and nicely thank you very much you really helped me😊

[@nehasathe3628]

Nice example .. though it seems like you made a mistake in red and blue count in part 2 where blue is picked in the first attempt..
Green should be 3/9 and red should be 5/9

[@GlenTanMath]

Yup you are right. I made this error many years back and uploaded a new one to clarify :)

It is said 2 discs are picked without replacement...Why did u only pick 1 disc?? Total should be 8 since 2 are removed

[@justindarimoah-jl7ko]

I also have a question to ask.please clarify for me .....why was the green for the second pick 5 on 9 and not 3 on 9

[@GlenTanMath]

You are absolutely right. I made an error there. The 2nd probability you mentioned should be a 3 on 9.
Will rectify that very soon in a new video. Thank you for pointing that out.

[@PeachandMario]

What about the combinations?

[@GlenTanMath]

Hi in terms of the combinations (outcomes), they are naturally listed out at the right side of the Probability Tree drawn.
For example, BB stands for Blue,Blue.
Hope that explains your question

How can I join this live charting

[@AminDarot]

I think you made a mistake with the green colour and the red in tree diagram😮

[@GlenTanMath]

Yup. The corrected video is linked in the description. You know your stuff :)

[@Memorifoodwithlove123]

Thank you but I have a question?

[@saloadan7967]

Ask

[@saloadan7967]

After getting the probability of having blue disc why are we again finding green and red in the second section from blue

[@GlenTanMath]

Because we are in this probability experiment of picking 2 discs? And showing all possibilities is part of drawing out a probability Tree.
Not sure if this answers your question?

[@iu7037]

Thanks man! Nice example for my review/lecture :)

[@sherifat1650]

Why did you choose to represent not red with one when te total probability was actually 8 where 3 out of it had second not to be red, I do really like the second formula but I want you to please clarify it out

[@GlenTanMath]

This is because the total probability of any experiment always totals to 1.
This 1 whole is synonymous with "100% chance".
This method is a commonly used "shortcut" because all outcomes of an experiment must total up to 1.
- Since from (ii), we have calculated the probability of a Red being chosen among all outcomes, then the remaining outcomes must total up to this 1 (without having to calculate each outcomes individually).
Hope this clarifies

Thanks but you made an error on the second pic its B R G not B G R

[@GlenTanMath]

Indeed! Correction video shared in the descriptions :)

[@maimomirabel2685]

Thank u for this

[@lochi4821]

thank you so much 😇🥰

[@GlenTanMath]

You’re welcome 😊

[@Samsitex024]

Ur last answer this is 1/2 is not correct. Clearify

[@GlenTanMath]

@Samsitex024 Hi I assume you are referring to Part (iii)?
Which part of the answer do you not agree with?
Hope to hear from you to clarify :)

[@Piririrriririrrirri]

Not clear
