An Introduction to Conditional Probability

An introduction to conditional probability, pitched at a level appropriate for a typical introductory statistics course. I work through some simple examples in this introductory video, and a I briefly touch on the concept of independence in an example at the end of the video. I work through more examples (some a little harder) in my conditional probability example problems video: • Conditional Probabilit... .

Believe me, gentleman, you are really good at this!

[@jbstatistics]

Thanks!

[@barrowmeoct04]

I failed probability last year and retaking it this year. Your explanation of Pr (A|B) using the Venn diagram is so absurdly logical I am floored. It's 100 times easier to see than trying to use numbers and algebra. I've yet to learn how to understand concepts in this 'different' way.

[@hemm2333]

Best explanation ever had. I love when he says, please do me a small favour and don't memorise the formula. That's how every teacher should be ❤

[@battlecrusecruse9155]

someone give this guy a medal. he is clearing my basics, from the past 3-4 years just confused with this topic and has avoided it .have no words for your efforts really thanks a lot for such awesome video

[@maestro_100]

Informal definition + Formal definition + Intuitive explanation of the definition + examples + further insight on future topics=Amazing Video! ...Thanks so much!

[@jbstatistics]

You're very welcome! It's one of my faves.

[@Daniel-to5jd]

the best explanation I've found about this topic so far, thank you man

[@Andynath100]

Your explanation of conditional probability using the Venn Diagram just blew my mind. So much easier to grasp the topic when you get an intuitive explanation of the topic.

[@Francois6048]

people like you who put effort in helping others understand things are just great human beings. thanks

[@bryonthestingily]

Such high quality content. You have a gift for deepening other human's understanding of this stuff :)

[@jbstatistics]

Well, I can't ask for a nicer compliment than that! Thanks so much for the very kind words!

[@tonynikolaos3527]

@@jbstatistics Indeed, i went through a lot of materiaql on YT- and find your elaborations the most natural, relaxed, intuitive and clear. Kudos! ... and BIG Thanks!

[@BatterflyHigh]

This is the first time this has ever made sense to me!! Thank you so much!!!!!

[@cheezey3295]

Failed my probability test. This is one of the best explanations I've seen on this topic.

[@roy601912008]

Thank you so much for making this video! I just started learning statistic on Coursera, but the teacher there makes it complicated and way too difficult to understand. And then I found your video! You are a life saver. Keep up the good job!

[@kousalyadevi5209]

Thank you for taking the effort to explain the statistical concepts intuitively!

[@angela2366]

I have struggled and struggled with this and came across your video....wow....I FINALLY have it! Thank you so much!

[@qulummmdov6572]

High Quality content, well explained. You sir have my appreciation!

[@jbstatistics]

Thanks for the compliment!

[@Luke-nh5tu]

This is by far the best explanation I have seen, the visualisation of the notation applied on diagram is really helpful because it tells you the whole story. Thank you (one more subscriber)

[@sonwabilecira37]

Hallelujah!
Thank you. The first video to actually make me understand instead of assuming that the logic of conditional probability is inherent

[@foodtips8515]

Your explanations are very good. Real life saver

[@veronikav8436]

I watched lots of video on youtube but no one explains as clear then you, now i got conditional probability:) THANKS men

[@jbstatistics]

I'm glad to be of help!

[@Joe-km7xi]

This is an amazing video, my professor rushed through this in like 2 minutes. Thank you!

[@alvaromiro2931]

Cristal clear. I love concepts stepping on top of formulae!!!

[@jbstatistics]

Thanks!

[@predatox1779]

I have a prob and stats quiz tomorrow and this helped me immensely! Thank you very much!

[@monczokapplehelp]

Your are the best statistics channel out there, thank you!
Could you please do a video about equivalence testing? In a world of data sites getting bigger and bigger good old hypothesis tests are not enough anymore

[@sakshichawla8236]

This video helped me understand the answer to the question I was looking in all the videos .... thank you

[@emporia100]

The best video for introductory conditional probability!

[@spicyornot1787]

Made perfect sense. Watched several ones before.. but none made it this clear.

[@marcoventura9451]

Good content, good explanation. The calmness of te logic before the formulas.

[@siddhantbajpai5889]

The best video on Bayes theorem!
Kudos to you brother!

[@hareemabdulrauf1746]

this is the best lecture i have ever attended

[@jbstatistics]

Thanks so much for the kind words!

[@exia124578]

I'm having to retake Probability and Statistics this semester after dropping it last and seeing you upload has given me new hope for this semester. Thanks for the great videos man!

[@jbstatistics]

You are very welcome! I'm not sure how many I'll be able to produce and upload this semester, but I'll see what I can do!

[@jorgegonzalez-ec5fl]

Amazing explanation!!! I like that you explain the formula and don’t just tell us to memorize it

[@123XTSK]

A High level clarity has been provided....with intuitive values.

[@alexmorton5556]

Thank you so much! I finally understand the conditional probability formula.

[@leili1910]

it is the best one i have even see explaining the content thank u !

[@presmompatigilbert5515]

I am enjoying this more than I do with my lecture, thank you Sir

[@Kisembobusiness]

this is the best explanation of conditional probability ever. I love how the explanation creates a foundation for what independent events are. thank you sir

[@jbstatistics]

Thank you so much for the very kind words!

[@onurcam34]

Thanks a lot for these great videos. I'm learning a lot more than I did in college lectures.

[@jbstatistics]

You are very welcome!

[@rishabhsharma329]

Whatta legend. Helping my masters sail through !

[@lynnseto6004]

Thank you so much for making this video. It is so helpful!!

[@zineddine]

Fantastic! Especially when you said: do me a favour, don’t try to memorize the formula

[@cococnk388]

This is what i had at first:
S= (0,1,10,100)
A=S1(10,100)
B=S2(10)
P(B/A) = P(A n B)/ P(A) = (1/4)/ (2/4)=1/2 =0.5
What I did above works if an only if they (payouts) do have the same probabilities.... but the probabilities differ according to the payout.
Thanks alot sir

[@Ujamama]

Thank you so much for this video! It was really clear and well-explained.

[@jbstatistics]

You are very welcome!

[@Rsingh1]

Out of other videos this is superbest and at the top level because of sooo clear explaination i have imediately subscribed it..... Fabulous... Instead of focusing only on solving Qs through formulae .. Explaination of those is also provided.

[@jbstatistics]

I'm glad you've found this video helpful!

[@Lil-lc2di]

Thank you this video really helped! I've already watched several videos on the topic but they just confused me more :'). Really appreciated the diagram around 4:30 personally.

[@marcosandoval7260]

Great Job!. The best statistics channel on RUclips!.

[@jbstatistics]

It is indeed :) Thanks Marco!

[@Cleisthenes2]

I feel like the probability of me understanding statistics has increased given that I have now watched this video.

[@niconetz2008]

I'm 20 years old, i've studied this topic like 4 times and i thought that i had understood it. Now I really understand it

[@machinelearning2578]

Most brilliant and super explanation of conditional probability.

[@jbstatistics]

Thanks!

[@mxkep]

Great videos. I wish I found your page earlier in the semester.

You are very welcome!

[@Rsingh1]

Absolutely clear explanation

[@jbstatistics]

Thanks!

[@Rsingh1]

jbstatistics is there any video on multiplication theorem of probability

[@kengsamnang7225]

Thank you for share the videos ..!!

[@ameerhbaig]

Thanks a lot for this video.

[@LK-wv3xv]

this is really probably redundant from other videos but you explained what my math teacher tried to do in two weeks

[@ayanlodh6485]

It's a really helpful thank you very much for this video 👍👌

[@jbstatistics]

You are very welcome!

[@levonkhojoyan6402]

thank you so much,,your videos are very helpful
,,,,it would be nice if you create a playlist Probability theory for Machine Learning

[@jo-ekaimadrona6738]

thank you for this video!

[@cleanestboi5854]

i like that you promote logic and intuitive understanding, its the best way to be prepared if you have a deep understanding

[@jbstatistics]

Thanks for the kind words. This is definitely not a "how to" channel -- I try very hard to help students develop a deep understanding of the concepts.

[@AriaHarmony]

Thank you very much!!

[@benjaminhowe8825]

Hey I’ve watched a few of your playlists and am just writing this to ask you a general question. What’s the best way to learn statistics stuff in r? I’m an actuarial student I’ve done statistics but I’m just unsure what the best way to learn r. Any advice would be most appreciated

[@akhil1067]

Well said!

[@kanacaredes]

Great video

[@mridu5685]

THANK YOU SO MUCH!

[@rohansodha9555]

Excellent!

[@jbstatistics]

Thanks! This is one of my faves.

[@miguelfonseca1104]

you did well, the division part of the conditional probability really threw me off, but the way you explain just made me realize in non-conditional probability, the probability in a sense has a denominator of 1 which signifies "from the whole sample space", when you add given, you must divide to specify its a part of which (partial whole). Thank you. Other videos dont make that clear.

[@deepakdeepu5711]

Understandable

[@nafizkarim5191]

wow best explanation

[@shirshak6738]

i never swear but u are fucking awesome. I never understood this formula. I watched like 1000 video from making tree to everything. Now i can say i understand this formula. Thanks a lot. If i havent watched this video i wonder how many year i would have struggled

[@petraakbari846]

Thank you soooo much!!

[@ramniwasswami5554]

Very nice vdeos in probability

[@Thobanatif]

If i was able, I would definitely give this person a, "NOBEL PRIZE" 🏆🏆🏆

[@jbstatistics]

Thanks! I'd accept it!

[@lovebaking2503]

enjoy this video and with a total understanding!
