Bringing the set operations together | 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.

For free. For everyone. Forever. #YouCanLearnAnything

That's exactly what they do. This Professor just breaks it down so easy to where you can easily understand it, while the majority of the College professors try to make it as complicated and as hard to understand as they can.

I have a test on this stuff tomorrow morning and I'm so happy that you're covering the material I'm studying at this exact moment!

8 years later and still the best. Helping me in my grade 11 ty

Sal, I failed a high level maths unit because the lecturer was a weak teacher. Not specified to this particular topic, but just saying thankyou to you for the significant effort you put in. I love your work.

An Actuarial student.

KhanAcademy you are helping me a lot through school. Thanks a lot.

It is nice ( if using Venn diagrams) to see how set theory and logic connect.

I think he should put one more parentheses in the expression so to know which one we have to do first. For example: evalute A - B U C does not make sense because we don't know which operation we have to perform first and (A - B)U C is not equal to A -(B U C) we can verify that. So in order to solve this type of problem we should include parentheses to know which operating we should perform first and that's why I think the expression in this vedio should include one more parentheses so that the expression will see like this {A-[A intersection (B-C)']}U(B intersection C)

haven’t watched the vid yet but tyty sm 🙆🏻‍♀️ i’ll be learning this next week so i rlly needed this 🥲

I'm 18-got here from the movie "Interstellar". Although I have some difficulty understanding most of this, I'm trying to figure stuff similar to this out. Super fascinating, I've always been interesting in Science and Math. Scared stiff for college. Does anyone have any advice for me, or cool occupations you could recommend to me????

Why aren't the 17, pink, and star included in "everything in the universe besides 0 and blue"?

[jamesnoonan]

If Sal says it deserves a drumroll I’m not gonna argue with the guy.

Damm I wish you were my math teacher, you are the best =]

Why we will include 0. A/A will give nothing so it's a null set now. And we denote it by empty brackets {} not by {0}

[BeStar-fzum]

Any one else miraclesly got the answer correct with 😵 steps 😁😁

[stuffedstuff]

Set of all things in the universe ??
What if there are other universes

[Natsukashii-Records]

I really don't want to offend anyone but it doesn't get slower than this... isn't this taught in highschool too?
Aside from that, anyone not understanding this might be missing something more fundamental, there are 3 more videos on set theory so they should check them out. There they will find what 'Universal' sets are and what Unions and intersections mean. If they didn't know that, it's possible for this to confuse them.
