I figure the probability of the other child being a boy is 2/3. But then I'm not a consensus creature.
Woof, in the highly unlikely event that your admirable educational initiative takes off, maybe you can then start a dedicated thread. |

Woof,woof,
What a great teaser. To me this is horse racing all over, as we think we are told the relevant facts but in fact we know diddly squat.
How many children does the family have? We might think that it's two but you might be wrong. Even though they have eighteen kids it is still correct to say that they have two kids . Even though they have twelve girls and six boys it is still correct to say they have one girl. Is it any wonder I bet on favourites for the place?

If the family has two kids and one of them is a girl the other must be a boy - right Kenchar?.
