Intro to Conditional Probability

- เผยแพร่เมื่อ 17 พ.ย. 2017
- What is the probability of an event A given that event B has occurred? We call this conditional probability, and it is governed by the formula that P(A|B) which reads "probability of A given B" is equal to the P(A intersect B)/P(B). We look at an example involving the probability of being an alcoholic given that one is a man.
Conditional Probability Formula: P(A|B) = P(A and B)/P(B)

Ok
Wow what a fun video! Reminds me of "if then" statements applied to likelihood of real life situations occurring.
I entered wanting to learn math, and I exited with knowing I have a good probable chance of being an alcoholic.
PLEASE JVKWNCNDO
Fucking mood lmao

XDDDD
Arcadian what is your profession?
Took me nine minutes to understand what I couldn't get in a fifty-minute lecture. Thank you.
Same here! You saved my life!
Jesus Aranda it’s a 6 min video XD
@@Tintin-dm4ym his maths is weak 😂
@@adityashinde1079 lol, he probably spent a little more time on a particular concept!
This concept is so simple as well as complicated if explained badly. The visual representation means so much
Stop reading the comments and get on with your homework.

Redwillow of Wattpad, it’s too late my pet goldfish already ate my homework. I’m just studying for a test
Fuck you
i feel attacked
@@bakonator4845 fuck u
Took my professor 2hr to explain this topic and NO ONE could not understand a word of what he said while it took you like 5min to teach this and now I can solve all the problems he gave us. You're a lifesaver so thank you. Universities should understand having a PHD in math does not make you a good professor, being able to teach is completely different from having the knowledge. But you Dr.Trefor, have both the knowledge and you know how to teach math.
Maybe you was just familiar with the topic thanks to your professor and video just served as a resource to ground your understanding?
@@alang.2054 nah, most profs arent teachers w/experience. a bunch of it is just funding for researchers. Theyre just given a syllabus.
Ur learning secondary school level maths at uni??
Who’s here during covid19 online learning
@@DrTrefor lol
I am doing statistic online and it is driving me nuts 😂
@@DrTrefor The probability of that occurring is beyond certain.
ayan aden this topic is the most stressful one for me and it’s my second time taking the class 😣
Good luck everyone with your online courses:)
You explained this WAAYYYYY better than my professor and khan academy COMBINED. Not sure why they made it sound so damn complicated
Yeah, it is the only video (I saw) that gives the meaning behind the formula. And this is exactly what I want.
People understand words better than formula but at the end of the day a formula is what you need to solve maths and no.
Please note : I came here looking for formula..I guess I should check khan academy..lol
@@suyashpal803 the formula is literally right there at 1:15. he even shows an example of it.
As someone who is hard of hearing, I really appreciate the effort put into the subtitles, thank you.
love you
Thank you!! I now feel ready for my exam tomorrow 😅 (anyone else in the same boat?)
yes
yeah have my exam in a week
Yes
Tomorrow is my exam
I have just came washroom from exam hall.
Exam is going on.😁😁😁😁😁😎😎😎😎😎😎😎
this man really summed up what an hour's math lesson couldn't in less than 10 mins
legend
I have a test tomorrow and I could never do conditional probability, but now you've made it seem so easy, so thank you!
Teachers at Cerritos College teach similar topics but some of them possibly have their bachelor's degree. Most of them are probably from Long beach or any city using the beaches/towns and cheaper places to live.
Same here 😢
I don't know how could people dislike your video it is harder to get than a whole discrete Math given by such a very good teacher like you, Good luck and keep awsome!
This video was released on my birthday 4 years ago, and it has inadvertently been quite the present only now. Thanks for the aha moment, Dr. Bazett.
You're a lifesaver💓Finals are coming up and this topic was giving me a hard time. Thank you! I'm definitely subscribing to your channel!
The best description that I have found. The venn diagrams are most helpful. Thanks
Sir i searched that how conditional probability formula came. No one explained. U explained it in so simple and in beautiful way. Thank you sir
I have watched crash course and my prof's lectures 5 times by now and only now do I get this formula, THANK YOU
Thank you very much, your proof have solved my question that haunted me for a year! Keep up the good work! Thanks a lot.
BEST MATH CHANNEL!!! Thank you for making conditional probability so easy to understand.
Sir.... My concepts are crystal clear now thanks to you. My prof was rambling on and on for 55 min and I couldn't understand anything, but you literally made a 6 min short video and voila!
Been doing an assignment for maths the topic being chance, it asked to explain conditional probability, this is so clear and so easy to understand! I'm actually pleased with myself for understanding something so quickly!
Jack Whitehall you are a lifesaver bro
Really awesome video. Currently taking stats for electrical engineering and I really liked this conditional probability description
I'm studying general engineering and I did not have a lot of statistics in my curriculum. The bit that I had I have already forgotten again. Now I need a LOT of statistics for my master thesis. You are saving me so much time! Much appreciated!
beautiful! It's been 3 years since I first saw conditional probability and now this is the first time I actually get it
I'm taking a statistics course and this just helped me understand the concept so much better. Thank you so much!
This really helped me to finally understand why does that formula work. Thanks!
So glad I found your video. This concept actually makes sense finally. Thank you! :)
THANK YOU SOMEONE FINALLY EXPLAINED THE FORMULA WELL ENOUGH FOR AN IDIOT LIKE ME
and another idiot like me too, haha
What a simple and efficient way to explain. God bless you sir
Oh gosh, I finally understood the intuition behind this formula. Thanks a lot!
Amazing video. 10/10 love the enthusiasm AND ACTUALLY HELPED ME UNDERSTAND THIS FORMULA BRUH. I owe u a great debt of gratitufe
wow, hours of suffering undone in a six minute video. Lifesaver dude, thank you
Sir your way of teaching is much better than other. Love from India.
Thank you so much for this Dr. Bazett!
Really succinct and clear explanation of Conditional Probability! Came here after not being able to understand my lecture slides.
Thank you for breaking it down to a level that could actually be understood.
Didn’t really understand this when studying in high school
Thank you for helping me clearing concepts with one short video ❤️
Thank you,you made all my sceptical thoughts deploy.Awesome video,
A good video with clear and appropriate emphasizing on the key point
I got to 5:30 and a massive freaking lightbulb went off in my head. THANK YOU
ty so much! saved my life! this is the best explanation i have seen so far
Really helped me a lot... so proud of a student of urs... keep going... thank you brother...
The concept has been explained comprehensively. Thanks a lot !
this was super helpful keep it up and never stop what your doing
you're a wonderful teacher, can't thank you enough
BLESS YOU!!! I can't ever understand my professor who's lectures are an hour and 40 minutes long, and I just learned it all in 6 minutes!!!
pog
this is amazing you answer all the questions and made everything clear best ever i'm definitely watching the next video for more examples that's liked and subscribed.
tysm istg my teacher tried to teach this and like 10 other things in one day to try to get us ready for the state test but you helped me more than she did
Thank you so much, you helped me understand probability in about 7 minutes what my tutor spent months trying to get me to understand.
Got to love the way you explain. Great video!
This was very informative and I understand the concept much better. I think I’ll reward myself with a shot or three
I watched all of four different videos about conditional probability and still didn’t understand it until this video. Thanks!
going into my final exam in a couple hours and I finally understood this concept omfg
Good luck!
whoa, you explain this better AND in a shorter amount of time, then the MIT guy. more videos please!
The MIT guy is too busy trying to impress you with his brilliance. He treats us like he doesn't have time to school you. 🙄
thank god you have videos on probability.
Why can't all prof be like you?
thanks man for this crystal clear explanation. you are really a king
Excellent video Professor, I read 10 pages of a statistics book and couldn't understand anything until I saw your video.
This all finally makes sense. You're God-sent; thanks a bunch!
Thankyou so much ,
Very well explained..., This topic is one of the topics in the syllabus of of competitive exams m going to appear this month (in India),
I checked some your videos and those are really helpful... Thanks again 🙏🏻
Just now I saw some of your videos, sir
its quite impressive, you have got some unique style of teaching. Keep Up your good work!
Finally makes perfect sense to me. Took three videos to nail the concept. This topic has really frustrated me and made me run away from probability. Now I understand what my problem was: I couldn't conceptualize the difference between probability of A and B and probability of A given B. So in my head it sounded as though A given B meant A and B.
Very well explained. Thank you for this!
So young and so brilliant. Thanks God for people like this👍. Respect
Perfect explanation. Excellent. Thank you
Oh my gosh thank you, I was overthinking it so much. I have an applied statistics midterm tomorrow!
Really simple explanation, the venn diagram helped a lot
Well explained. Thank you for tutorial!
I am so grateful for this. I finally understood.
literally so helpful. cant thank you enough
Amazing, you explain it so well. Thank you so much sir!
loved the explanation Dr
crystal clear presentation. Thank you !
Sir, you have been so helpful. Thank you so much
very helpful and straight to the point, tysm
Thanks for making this video.
Very Helpful.
wow, you explained tyhis so well! better than my professor. thank you so much!!
Thank you, you are an excellent teacher!
Great explanation! Thank you so much.
Very helpful! I'll come here frequently!
Impressive video Dr.Bazett
Thanks, you make it so simple!
Brilliant video. Well explained!
Thankyou for this!!! So straight forward!
Wow, just amazing! You saved my day!
The visual aid was very helpful❤
Now I really understood it after so many failed attempts. Thank you!
the probability that i have understood this given im an idiot is remarkably high. many thanks.
Excellent, excellent, excellent explanation! Thanks you!
if you are a man, and a russian, your probability of being an alcoholic is 100%
бодяныч what if you are a woman?
Piyush Uniyal, if you are women in Russia, probability of being single and have 10 cats is 20%, other 80% is for being married and get beaten by your husband👍
@@bodzinho3273 really?
why so serious?
бодяныч what about the probability of being a Russian man and committing suicide?
probability of becoming president in russia?
wonderful explanation
You nailed it sir.
Hey man I do like that you do explain the meaning behind the equation, that is how we should learn maths in all stages keep it up :)
Thanks for the great explanation!
This was a great video! It helped me understand conditional probabilities easily and quickly! Thank you!
Do you have a video on the normal bell curve? or do you know where I can watch a good video on it? Thanks!!
Thanks a lot for your videos. They are really help to understand.
I'm an average student. I have been searching for the perfect explanation for conditional probability for a long time. My search ends now. Thank you!
Couldn’t explain this in a better way.Tysm
Great explanation, excellent example problem thank you!
Best video I've seen explain this yet
