The probabilities don't add up to 1. They add up to just a little more than 1 - 25/24. I think we can just change all the denominators to 25 and everything will be alright.

Thank you, you saved my exam/life. My professor didn't bother to teach it yet his exam had me looking for the Cov and correlation.
hahaha they do that all the time
Perfect well done. Simple, short and right to the point. Thanks WBM.
Ending should be correlation not covariance.
Rajeev Khuttan Silly error on my part, apologies.
I will annotate the video to correct it!
Thanks
@@WelshBeastMaths 9 years later not annotated haha
Hi i think you made a little mistake at the end, instead of covariance, correlation, thank you
You are an absolute savior. Thank you so much.

at 8:13 you had stated the fomula to be cov(x,y)=corr(x,y)/sd, as opposed to the one at 5:33, where the values are switched. which one is correct?
And I wa so confident for my assessment, now I’m here at the comment section wondering if I’m the only one who notices the switch up…
You saved my life, thanks a lot!
Bro where are you we needed more of this topic
Thank you so much, been struggling with this for what seems like an eternity now. Best vid on this out there
This is so cool. You made my day. Thanks a lot. I was lost as to how to get E|XY| but now I know.
Same. It's weird I couldn't find it anywhere else!
mate, you are so goated
thank you so much, was looking to solve E(XY) for so long
Excellent video. Studying for the P1 exam for actuary and it helped a lot!
Thank you, this was helpful
Useful, thanks.
how do you calculate E(X) and E(Y)?

a little late ig lol
Thanks, I'd like the video but it has 420 likes and I'm not gonna mess that up
Please next time show how you derived the marginal expectations
You are awesome!!! Thanks for the video.
thank you so much ^_^ this was very helpful!!
yu did the vice versa there....but its nyce
Thank you for this!
That helps a lot! Thanks!!!
thank you so much, im actually looking for this .may god bless you. I subscribe :)
thank you so very much. Very helpful video.
much effective tutorial
thanks for the video
THANK YOU SO MUCH!!
Thanks brother for covariance formula
Thanks a lot bro.. u saved me 🙏
In 2024 i'm watching this video for my finals THANK you sm sir ❤
I really enjoyed your mini-series videos. Very clever and very practical explainations. Thanks
wasn't the E(x)=24/24? how did you get 29/24?
Same question
very helpful ty
Thank you so much!!!!!!!!!!
Thank you!:)
Thanks!!
thanks
Thanks a looot =)
The sum of all probabilities in your values is 25/24, that should be 24/24=1
