Hi everyone, there is an error in one of the parts and the entire correct solution video can be found here instead : • CCSS Math - Probabilit... Thanks to one of our viewers for pointing the mistake out :)
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
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.
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
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
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?
❤love from Africa you explain so detailed and nicely thank you very much you really helped me😊
Thank you sir. I am doing my exams tomorrow and this video has been helpful.

Green should be 3/9 and red should be 5/9
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
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
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.
Thanks man! Nice example for my review/lecture :)
Thank you but I have a question?

Thank u for this

After getting the probability of having blue disc why are we again finding green and red in the second section from blue
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?
Ur last answer this is 1/2 is not correct. Clearify
@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 :)
Thanks but you made an error on the second pic its B R G not B G R
Indeed! Correction video shared in the descriptions :)
thank you so much 😇🥰
You’re welcome 😊
