Universal set and absolute complement | Probability and Statistics | Khan Academy

Missed the previous lesson?

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

hes really good at wwriting with a courser

Yes, you should study logic if you want to learn set theory/proofing and such...try 'Logic for Dummies' for a crash course (and also pick up a copy of Schaum's Outline of Logic as well)...you can also grab a copy of Keith Devlin's "The Joy of Sets" and skim it, just to get an idea of that area of math...
Maybe even pick up a history of mathematics book as well (Grattan-Guinness's "The Search for Mathematical Roots" is pretty advanced, but worth looking at--again, to get a sense of the subject).

Look those up online and see if you can figure out why...(research 'field extension' and contrast the axioms of different set theories--i.e. proper class). Then turn back and take a look at the basic divisions (NZQRC) and see if it makes sense to you (also, you should double check the definitions, at least 2 of those are directly related to the point of almost being synonymous).

Thank you so much. This series is helping me to understand my "MTH/221 - Mathematics for Information Technology" course a lot. The text is extremely vague, and they do not provide tutors.

U = Union, U = Universe ... ! Don't do that !

Thanks a lot for this informative video, it helped me understand it better. I study computer science and one of my subjects is logic and mathematical techniques . to be honest i don't understand that much from my teacher because i don't like the way he describes things. I have my first exam tomorrow. Wish me luck ! <3

youre a million times better at teaching then my rusted old teacher

Exactly. The set of all sets is smaller than the _class_ Omega. Omega is the _class_ of everything and is not a set.

Dude it really cleared the mathematical reasons about why my brain left me



And I can't even type properly...

[Thexmadshooterx]

types of kitchen utensils and italian food in the universe xD

Sample space can be represented as Omega.

This topic is very easy, the only problems are memorizing the symbols.

Nptelhrd has videos on logic starting with propositional logic. I'm only on the third video though.

If there is an Absolute Complement, is there a Non-absolute Complement?

[jeremymiller]

What about hyperreal, sureal, surcomplex, and hypercomplex numbers?

[jeremymiller]

Ok. Do I need to understand much logic for this? I understand what the symbols that Wikipedia uses for the first two axioms of Zermelo-Fraenkel set theory. Being able to read logic and being good with manipulations in logic are two different things.

Z for 'Zahl' pronounce 'Sal' in German not jal ;)

[jeremymiller]

So much possible stuff to learn. Where do I start? :(

There is no "universal set", which is the set of all sets. You quickly get into contradictions if this set were to exist. The universal set is just way too big to be a coherent set.  There's no need to speak of a set containing "everything". Otherwise, what you do in this video is just substitute the letter U for R, Q, or Z.

In an exam when they ask for n() does that mean the number of elements added together or how many elements there are in a set?
