Isn't the probabilities suppose to sum up to one and in the table the entries sum up to 25/24.

[@WelshBeastMaths]

Konstantin Kotsev Please see my reply to this comment on "Part 2". I copied a number down wrong, you are indeed correct!
Thankyou for watching

[@the_asadali]

exactly, what I was looking for.

[@muhammadahmed6889]

Me also.....

[@hanzashehzad3301]

Superb man superb i cant believe that its much easy ❤️

[@andrewvernon9480]

Thank you so much, exactly what I needed

[@burgerlover57]

Thanks dude, straight forward

[@sofiesbr2667]

Thank you so much for your help lot of appreciation 💕😊

[@SoloPro]

good vid but you should use a proper example since probabilities cannot be more then one and the marginals should also add to 1. But still a very good video so thanks a lot

[@amrsleem7508]

Thank you for posting

[@jonglee9917]

The probability sum is 25/24 greater than 1. Is it OK?

[@sulgrave_]

The units aren't in terms of a probability. "25/24" is in terms of the original events for X or Y. If you performed this experiment over and over, you'd get a value for Y somewhere around 25/24.

[@waterwaveworks]

That marker is good asmr

[@thorisor2428]

This is not valid because they sum up to 25/24

[@TommyR96]

Yh it’s supposed to sum up to 1

[@juamocoustic]

How did you come up with all the something/24 values in the table itself? That's what I was looking for, but I don't know under what name I can find it.

[@1rokamonas]

same. He kind of skipped the whole purpose of the video (if one looks at the video title)

[@juamocoustic]

It's been a couple of months since I learned this, but if I remember correctly:
For the top-left value (3/24) you calculate P(X=0)*P(Y=0). That's the scheme you use for all values. Then apply what was mentioned in the video to compute all of those. Hope that helped

[@merafhemodumo6069]

why do we have two expected values

[@sulgrave_]

X and Y have their own distributions of values, so E(X) and E(Y) will take separate values

[@buraksener3113]

why you wrote 12/24 at 1:48 i thinkit should be 8/24 if i am not wrong

[@MrDessty]

Hi, is marginal distribution samething as mean(x)?

[@suryayadav9182]

the cringe of the marker sound
