Intro to Probability 4: General multiplication rule; Intersection; AND

Walking through the general multiplication rule

[@BobBeatski71]

Bloody hell, these short tutorial videos are fantastic.

[@ericjobin4382]

I have a man-crush on this guy! Not only does he explain really well, but I got an A in my college stat class because of him. He makes stats easy for anyone. Thanks Mr. Nystrom you are the best. I wish I had more teachers like you.

[@richardgordon]

Thanks Mr Nystrom was struggling with the explanation of these concepts in my CFA course and you made them crystal clear! Respect!

[@deannaferko-chinca1539]

I am 50 and in my final class before I graduate and I could HAVE NEVER past Pathway and Stats without this guy!!!! You are the best! Thanks for explaining everything with such ease, natural, and applying to everyday things. Wait... and FUNNY too!! Don't stop teaching. 👍

[@rubendevine8346]

how many times were u held back

[@kwanitayates5580]

You saved me from a second melt down!!! Thank you so freaking much for explaining this perfectly.

[@mahatmagandhi1435]

What a way of teaching

[@anoopramrayala6990]

Supercalifragilisticexpialidocious 👌not only this but other videos too Lot of analysis in regression,woow

[@kristynehissner5115]

Thank you for these videos! I'm taking college statistics and these videos helped me to understand it. I wish there were more teachers like you because you explain things so clearly.

[@jenniferannewerezak6897]

I'm in "intro to Stats for scientists" and I find your explanations better on every level than what I get in the lecture hall!!!! (No offense to da prof, if he ever happens to read this :P) Thank you!

[@ignaciogarciaormaechea3287]

muy bueno !!! pedagogico y entretenido !!! gracias !!!

[@nicknguyen77]

An intuitive explanation of independence.... that's really good. In experimental Design of Experiments (DOE), widely used by process engineers, this would be flagged as 'significant' or 'insignificant' factors or interactions... I like how Mr Nystrom gives an intuitive understanding of independent factors...

[@brianshrode72]

I love this guy's personality!!!

[@arinapliushchik5733]

Oh no! Why did you stop with these? I was just on the verge of hoping to grasp probability after all. Maybe Patreon wasn't popular (or didn't exist in 2015), but I'm sure many of us would support you nowadays so you could continue making videos! Please, consider. And thank you for these wonderful tutorials.

[@EAHall]

Thank you Mr. Nystrom. I am taking Mathematics for Liberal Arts and I need this type of detailed teaching. My professor is awesome, don't get me wrong, but I'm really receptive to animated and visual teaching. Thank you for being you!

[@zahidshahkhan6898]

very interesting teacher....I salute to mr Nystrom...

[@seasalt3188]

THANK GOD FOR YOUR DRY ERASE BOARD AND PENS> (Bless you child!) My ears can handle this! Great teaching style~keep it up!

[@mihaip6449]

Brilliant as always! Great explanation!

[@peaches9223]

Thank you for this video. Really, you have saved me loads of time or crying myself to sleep. I am working on a college Probability and Statistics course and I was really struggling with this one simple rule. Thank you so much

[@DarkMelodies-hv9wf]

im still crying. Good explanation tho but my Brain can't fvcking compute I hate myself

[@MessedUpGaming]

Needed this like 2 weeks ago for my discrete mathematics course!

[@Guns-N-Nurses]

stumbled on this video now I just have to subscribe! Great job on making the subject matter more interesting! thank you!!!

[@engineeringskills641]

Teaching style is very good...

[@matikotiko6495]

good explaination and very funny at the same time,which makes learning very interesting

[@crtnnn]

AMAZING!

[@kevingenova1746]

I feel like you'd fit well in the Big Bang Theory.

[@warriors_of_light5559]

Loving it!!!!:)

[@user-pl7bx6dk5q]

U SAVED MY LIFE

[@cylurian]

Hello MrNystrom. After learning all these rules in probability, what topic is next? How do you use this next?

[@ShreyMittal16]

Coolest guy!

[@paulinechiu7462]

OMG I LOVE YOU

[@sarahfellows3074]

Hi, could you please help me with this question; why is multiplying variables different and or better than adding variables together? Many thanks. P.S. My question is to do with frequency distribution rather than probability but I'm pretty sure I heard you say (in another vid) that multiplying a variable allows you to see the result on a bigger scale and therefore differences between variables are more clear. My tutor described it like multiplying variables means if someone scores zero for motivation and they score 4 for talent and 5 for practice ..if you just add them together - ( e.g.9 would be composite score of how good drawer they are) - so the zero will counts a lot in adding variables to get frequencies. but if you multiply all the variables, 0,4 and 5 then the 4 and 5 will compensate for the 0 in motivation and will make the other two variables (that all come together to make the same thing - how good drawing someone is) more of an equal frequency distribution. P.S. apologies for long and protraction but any light you can shed on any of this would be much appreciated. I understand if you don't know what I'm going on about though as I am only just grasping what I am saying myself in small glimpses.

Let A and B be disjoint events and such that p(A)>0 and p(B)>0 are they dependent or independent??

[@ps4909]

Awesome explanation

[@sooome9294]

I have a blockage and it still does not make sense, help, I need to get through this blockage and don't know how.

[@arielle-cheriepaterson3317]

whats your skincare routine?

[@sohailsattani]

Thanks.. This really help me to understand the topic.. Can u pls solve below question: A study by Peter D. Hart Research Associates for the Nasdaq Stock Market revealed that 43% of all American adults are stockholders. In addition, the study determined that 75% of all American adult stockholders have some college education. Suppose 38% of all American adults have some college education. An American adult is randomly selected. a. What is the probability that the adult does not own stock? b. What is the probability that the adult owns stock and has some college education? c. What is the probability that the adult owns stock or has some college education? d. What is the probability that the adult has neither some college education nor owns stock? e. What is the probability that the adult does not own stock or has no college education? f. What is the probability that the adult has some college education and owns no stock?

[@shibramon]

You r awasom

[@somcana]

Can you do the same concepts using contingent table? Thanks

[@moha081]

Just Waoooooo man :)

[@deannaferko-chinca1539]

Hey, can you upload some Two Way Tables for probability??

[@jenniferannewerezak6897]

Oh no! I've reached the end of MrNystrom's probability series. If only there were moar! (*Ahem* Total Probability Rule, Bayes theorem, Poisson, Binomial*cough hack cough* Did I say anything? I don't know what you're talking about!!! :D)

[@catrachoboy79]

Wait wouldnt the Prob of being blue and even be 1/5 since there is only 5 evens and not then?

[@majorbadidea]

kenny maldonado put 2/10 and 1/5 into a calculator :)

[@santerraniccals]

Do you have an email so you can help me with my homework I cannot understand if I am right or not

[@himanshipuri8461]

Hot + Teacher = MrNystrom 😍

[@vivianjoyasimetin429]

Livelyyy and its funny hahaha

[@anuradhaanbazhagan1808]

Find the probability Intersection of A and B if it is not independent? P(A) = 1/4 P(B) = 1/4 can u please help me solving this?

[@yvetteurbina4813]

handsome and intelligent

[@wasimsiddiqui3778]

What is the probability of this video getting number 1 on 'Stats mystery resolved' list? >>>>> 100%

[@jesica20001]

I hate how he talks but damn I understand this topic good af now. Thank you.
