Intersection and union of sets | 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

7 years down the line and this guy is still saving my life

[mary-kate]

my professor literally overcomplicated these concepts thank you SO much

[Nissisaurus]

Thank you, Mister Handsome-voice-man. This has been so helpful. 😭 🙇‍♀️

[fatimamahdi]

tysmmm i actually have an exam tmrrw and I was literally was breaking my head understanding this, you don't understand how much this has helped me

[chhunchhim]

I can't get over the fact that you have such nice handwriting that is understandable and legible, even on digital print. Keep up the awesome work!

[elidrissii]

THIS IS EFFING AWESOME!
I can't believe Khan is teaching us about Set Theory. I think he's finally starting more advanced Math.
I feel like I am in a dream.
I already know most of this stuff but nothing equals Khan's level of delivering a message so I'll watch them all at least three times each.


Thank you, Sal.

This is really great Sal! Thank you very much. I sincerely hope you will do more videos on discrete mathematics.
If you have some spare time I would like to see a video on the barber paradox, should be a fun brain teaser for all ages.

[robman]

I must compliment you on how well you taught this subject.

[kittenk]

this helped me so much!! i'm homeschooled and it doesn't explain very well so this is were i came and i'm happy i did.

[vault]

THANK you are a better teacher than the dinosaur that I have for a teacher

[admudesigns]

math test tomorrow!!😭😭 hope I'll understand this now!

[Salsajaman]

I'm in calculus 1 in college and I feel stupid for looking this up

[wywlonl]

This was exceptional. I am self studying real analysis rn and I honestly cannot see what the need for over complications when explaining simple concepts like this

[Itsnatehart]

Your videos have made my studying more understandable. Thank you so much, I am considering donating just because of how great of a teacher you are, and the fact that you are have this content available online for FREE. Completely blows my mind, you are a true hero.

[unpickel]

i was crying over math and my bf sent me this 😭🙏 bless

[PankajSingh-dcqp]

What is the intersection of set 1:{t>5} and set 2: {6<t<8}, where t is a random point in the interval [0, 10]???

[Kage]

5:24 Shouldn't you also cover the intersection since you write X union Y = {3, 12, 5, 13, 14, 15, 6} but you don't cover 3 in the drawing.

[realStYliShGuY]

Thank you so much. God given professor

[denadagjyzeli]

Thank you so much😂 that was very helpful. I never quite understood my teachers in these chapters but you explained it so good!

[bluebird]

great explanation ...really helped..thanks
