Well made video. Took me a while to truly grasp concept, this hammered in the concept. Thank you very much.

Discrete mathematics is the weirdest thing ever to me. I learned all this math leading into calculus. Tearing my hair off trying to understand all of these abstract concepts. After starting discrete math things are alot different. No more integrals, derivatives, etc.. Everything I am learning now is just a bizarre combination of verbal logic and math in order to reach some level of conclusion to problems such as "if a then b, and b is true. therefore a is true". Combinations, prediction, algorithms. I wonder why I even need calculus? I don't believe calculus prepared me well enough for this.

Calculus and this are two different things. Just because calculus is not very relevant to the discrete maths you're learning, doesn't mean you don't need calculus.

Thank you. I've now gone through three professors who have failed to explain this topic very well. I don't blame the professors too much. After all, at college and then master's level a lot of learning is on me. Great job with this video! I've started to understand this in a way I didn't before.

At 8:18 you said minus the intersection of all three intending to say that you add the intersection of P60 intersected with P04 intersected with P42.

So treat 60 , 04 , 42 as their own numbers is the main trick, which makes figuring out what P60 , P04 and P42 is equal too, which is 9! . Nice straightforward explanation and derivation on A U B U C

how the heck is he getting 193 from 3*9!-3*8!???

He got it by separating like terms! 3*9! is the same as 3*9*8*7! 3*8! Is also 3*8*7! So we can say the equation, 3*9!-3*8!+7!, is also just 7!(3*9*8-3*8+1) by bringing outside a 7! Which is also simplified as 193*7!

AUBUC since the A = english B = frenchetc. and the overlapping between A and B is the students whom study english and french repeat for AC CB then add the middle you can calculate any group with that

It means that we need to mathematically show that the inclusion/exclusion principle produces the correct result in every case. Not sure if u care 4 years later, but still xD

This is exactly the Inclusion-Exclusion formula applied to the example. The formula for n=3 different sets can be seen at around 6:56. The general formula really isn't in that video I think but you can find it everywhere on the internet if you just search for it.

He changes all the terms to be multiples of 7! so they are easier to add together.

Rewrite 9! As 9*8 *7! And 8! As 8 * 7! And you can reduce and simplify if terms of 7!
