This kind of feedback is exactly why I like to post drafts early. Expect this example to magically disappear very soon :)
Ambiguous: "In a family with two children, what are the chances, if one of the children is a girl named Florida, that both children are girls?"
More clear, and emphasizing the importance of precise wording when discussing probability: "Among families with two children, with at least one of the children being a girl named Florida, what portion have two girls? (Assume that all names are chosen randomly from the same distribution, independently of all other factors; and sex is determined as by a fair coin toss.)"
I re-read the chapter and decided that example was doing nothing except confusing half the audience and antagonizing the other half.

Peace.
