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.
You are an absolute savior. Thank you so much.
Thank you so much, been struggling with this for what seems like an eternity now. Best vid on this out there
You saved my life, thanks a lot!
Hi i think you made a little mistake at the end, instead of covariance, correlation, thank you

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
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!
Bro where are you we needed more of this topic
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…
Thank you, this was helpful
mate, you are so goated
Excellent video. Studying for the P1 exam for actuary and it helped a lot!
thank you so much, was looking to solve E(XY) for so long
In 2024 i'm watching this video for my finals THANK you sm sir ❤
thank you so much ^_^ this was very helpful!!
Useful, thanks.
Thank you for this!
how do you calculate E(X) and E(Y)?

a little late ig lol
You are awesome!!! Thanks for the video.
I really enjoyed your mini-series videos. Very clever and very practical explainations. Thanks
thank you so much, im actually looking for this .may god bless you. I subscribe :)
thank you so very much. Very helpful video.

That helps a lot! Thanks!!!
THANK YOU SO MUCH!!
The sum of all probabilities in your values is 25/24, that should be 24/24=1
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
Thank you sooooo much!!!!!
wasn't the E(x)=24/24? how did you get 29/24?
Same question
Thank you!:)
thanks for the video
Thanks!!
very helpful ty
Thanks a lot bro.. u saved me 🙏
Thanks brother for covariance formula
much effective tutorial
yu did the vice versa there....but its nyce
thanks
Thanks a looot =)
lovely :)
thank you so much i was looking for this and i have an exam tomorrow thanks sir
thanks sir dont make silly mistakes
Thank you so much!!!!!!!!!!
thanks
