In the original problem you start by assuming 4 equally-probable cases Bb Bg Gb Gg [1] and you ask a question. Depending on the answer you are in the Bb/Bg/Gb or the Gg subsets. In your variant you need additional assumptions. Will the person always tell you the sex and name of the eldest? Or the names of the boys? “Michael is a boy” is not really different from “the youngest is a boy”. The probability of both being boys depends on why are you being told that. [1] Depending in the context the assumption may not be appropriate (a extreme example may be China). |
