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

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

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.

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

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

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

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

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.
