A Gender Balance Puzzler

Here’s an unusual puzzle, like so many puzzles of this type, alleged to be asked as an interview question at high-tech companies. It seems one is going to be locked into infinite sums: half the couples have just one boy, a quarter of the couples have one boy and one girl, an eighth of the couples have two girls and one boy, and so on, and thus … err …. But there is a way to avoid hard work with this puzzle. Jolly fun!

    Written for educators - and their students too! - this website, slowly growing, takes all the content Tanton has developed in his books, videos, and workshops, and organizes it into short, self-contained, and complete, curriculum units proving that mathematics, at all points of the school curriculum, can be joyous, fresh, innovative, rich, deep-thinking, and devoid of any rote doing! Let's teach generations of students to be self-reliant thinkers, willing to flail and to use their common sense to "nut their way" through challenges, to assess and judge results, and to adjust actions to find success. (Great life skills!)
