Good grief yourself, Charlie Brown. If you find a quote where I said it was either 1/11 or 1/6, please let me know. I repeat my earlier example, "Arci winks at the cocktail waitress, slams down his drink, then peers down her blouse. What is the probability a sexfest ensues?" In your mind, is that a "math" question? And how is that clearly different from the original question in narration and what it is asking?
You say people need to learn to do math. Yeah, and people need to understand the difference between a sentence and an equation. What's most disturbing is that some people fail to understand that if a large chunk or majority of readers read something, and come to Answer A when the answer is B, then the problem lies with the author, not the readers. Arci, I hope you've tracked down the author and posted 50 times regarding what a lousy job he did. Just because you "got it" doesn't make it correct. You are not the arbiter of how people interpret pieces of writing and how they should interpret pieces of writing.
