Why can you not frame it as: "a random family has been sampled, the sample family has two childs, one of them is a girl"?
I.e. without "discarding", just giving some additional, but not complete, information on the random sample. Is adding information about the picked sample the same as discarding all contrarian samples? Why is this relevant?
