Arci, you parsed the question so as to arrive at your answer, yet a rigorous parsing of the language of the question suggests your conclusion isn't necessary. Is my parsing absurd? Maybe, but it isn't incorrect. Is your parsing absurd? Possibly, and it isn't necessarily correct.
The word "chance" gets mentioned in primary definitions of probability, but not "percentages" or "odds" or anything really mathematical. I think you should probably look up the definition of "chance" while you're at it. Not much mathematical in that primary definition, either.
Why do you think the author of the question avoided a description involving plural throws and plural peeks? Why did he not use any mathematical terms? Why was it present tense? He didn't write up this question this way by accident.
I suspect you had no idea that the primary definition of probability contains no references to odds or percentages or any math terms.
It must kill some folks to realize they're as language-blind as other folks are math-blind.
