This video is uploaded because less than half of the viewers who responded to the Google form forms.gle/QJ29hocF9uQAyZyH6 says that they know some basics of combinatorics. So in order to make sure we are on the same page, I need to make this video. Even if you know these concepts, it is still worth going over to clear some concepts up. That said, I need a larger sample size to determine the overall math level of my audience, so please fill in that form if you haven't already.
Keep up the good work buddy! Itwould be nice if you could make a plalisy on olympiad mathematics ( just problem solving and possible applicatins of ideas in math)
Because those 5 shared destinations between the three airlines were also 5 subtracted destinations shared between the blocks of two airlines. If all airlines share 5 common destinations it means consequently that the groups of two airlines also share each of those 5. The process of subtraction of the shared destinations in groups of two airlines has the objective of not overcounting how many available destinations you can fly to, but it has the flaw that if the places are shared by the three airlines, those destinations just dissapear by the subtraction. So you also check when the destinations are shared by the three airlines to add them back in. I hope it's understandable and still useful after six months lol

This video is probably the best overview I've seen of Combinatorics.
Thanks!
Thanks
😊3b1b vibe.... So calming.
Really nice video. I've never seen the Inclusion-Exclusion principle being taught that way.
I immediately understand the inclusion exclusion principle using the venn diagram so I think it very much aided my understanding
The idea of overshooting when taking away the overlapping region is very easy to understand
Why do I not get good youtube recommendations like these!
The explanation is very good.
Thanks!
Excellent

What do you mean by "possible applications of ideas in math"?
@@mathemaniac Well simply put I meant some real good things to try while solving olympiad problems

Fantastic explanation! Thank you!
very clear explanation
Glad you think so!
Thanks alot !!! Cheers
What resources are you referring to in order to make these videos ?
Is it just me or does Mathemaniac sound like Lord Frieza?
Definitely got that elegant accent and tone
Why did you add 5 at 6:07

@@elicrotsn5085I had the same question and I finally understand. Thanks!
👍👍👍
Why did you add the 5 destinations all flights back the equation
I think because they were subtracted one too many times in the previous steps and so need to be added back in
