I’m not sure about the off-topic rules here, but how about this:
Why are some of the drinks so expensive, given that all of them are mostly water?
Sometimes we use the phrase “given that” to mean, “considering that”. Here, we do not mean, some of the drinks are not mostly water but we are not talking about them. We mean that literally all the drinks are mostly water.
Jumping in here: the whole point of the paragraph right after defining “A” and “B” was to ensure we were all on the same page. I also don’t understand what you mean by:
Most ordinary people will assume it means that all the rolls were even
and much else of what you’ve written. I tell you I will roll a die until I get two 6s and let you know how many odds I rolled in the process. I then do so secretly and tell you there were 0 odds. All rolls are even. You can now make a probability distribution on the number of rolls I made, and compute its expectation.
