If you mean that the space for this single experiment composed of two rolls (random variables X and Y) is the cartesian product of {x=1,x=2,x=3,x=4,x=5,x=6} and {y=1,y=2,y=3,y=4,y=5,y=6}, then I agree. But the fact that each variable alone

What did you mean with the following paragraph then? > Let's consider two independent rolls, X and Y. You can't compute the joint distribution P(Y, (X|E)), it just doesn't make sense as the two "variables" are de

To be fair, AMZN was valued at $400mn at the IPO and not $80bn (only in 2011 did Amazon reach that valuation).

Are you suggesting that films can be classified as either “union” or “amateur”? Star Wars is an amateur film then. And saying “amateur porno” is redundant.

I wouldn't classify as "amateur" a commercial movie where the lead roles are played by professional actors, but that may be just me. The downvotes I got agree with you. (Being a bad movie may make it look "amateurish&quo

What's "amateur" about that? It seems that the word appears only in the title. Edit: he had a $25k budget at least (over $150k adjusted for inflation) and while it was his first movie he hired professional performers and the

What does the word “incentive” mean to you? People do drive in London, so they have their reasons (however unreasonable they may look to you). And probably “fun” is down on the list. Unless you think, Berra-style ( https://quotein
