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

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.

Thank u for this

thank you so much 😇🥰

How can I join this live charting

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?

Thank you but I have a question?

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

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

@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 :)
