Compound probability of independent events | Probability and Statistics | Khan Academy

You'll become familiar with the concept of independent events, or that one event in no way affects what happens in the second event. Keep in mind, too, that the sum of the probabilities of all the possible events should equal 1.

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.

That is the best damn quarter I've ever seen drawn on a computer.

[Shuma...]

Absolutely love this Channel...

I understood something that an hour of Online Class can't Explain Clearly.

[rikard]

seriously, why cant professors be as concrete as Khan? By making something easy and concrete, it helps many people when you face a harder concepts/problems there you really have to think and use those basic things to understand it. This is basic and I can understand it but every individual have to verify if this is a hard problem/concept or not, not by professors who thinks everyghing is easy... For me this is an obvious concept but I couldn't use the formula on my text book but now I can! THX

Online classes are the only reason I’m here

Currently studying for the Praxis and struggling with this (I'm a Lib Arts graduate so math is a struggle). Whenever I turn on a video and hear this guy's voice, I'm like, "YESSSS I'm actually going to GET IT!" Hahaha

[mr.earthworm]

Greetings, I was sent by the gods of online school.

[LinaSlayz]

Thank you so so so much
I’m in 6th grade and I take advanced math, and this was the hardest concept for me
This video is like magic. Everyone show this guy some respect for explaining something so complex in 5 minutes 🎉

[scottiusnevious]

This guy is such a wiz. I followed along and now understand my assignment.

YOU'RE AMAZING!!! BECAUSE OF ONLINE CLASSES ITS HARD TI UNDERSTAND EVERYTHING MY TEACHER HAS GIVEN US TO STUDY AND THIS IS A LIFESAVER

[romancedesepana]

That's the best fucking drawing I've ever seen.

An easier way of obtaining all possible outcomes for three coin tosses is to create a tree diagram. In this way, you'll be sure to account for every possible outcome.

[justabanana]

Thk u this might actually help meh with my probability math test tomorrow

[LilSadGoose]

I shall master this and impress my teacher

[Desperatechanging]

Reminded me of high school. Your video makes it all easy to understand!
Cheers.

[clumsycaden]

Online classes are hard, this makes it easier. thx

[zulfiquarabbas]

it was heart warming when he gave attention to Tails

[cathy]

I can't believe I'm doing Khan Academy, this has been a long time dream :)

[otmanalami]

Please I have a question ^^Thank you in advance: The first person is flipping a coin 50 times, and at the same time, another person takes out randomly 50 balls from a hole. ( the hole contains 100 red balls & 100 blue balls )
we give 1$ to the person on each head he gets
we give 1$ to the second person on each red ball he gets

The question: what they may get $$$ both from this experiment?

[skylette]

Greeetings im a time traveler and as i can seee whats happening from beyond.

[aabatterysensei]

My math teacher took 1 hour to explain this thank u for explaining this in one minute
