Jackie’s two sons, Lee and John, have chosen two very different careers. Lee is a sheriff, John is an outlaw. Both careers involve six shooters and illegal paraphernalia. Both Lee and John have 2 six shooters each (each son only has two hands…).
Lee is not a very good law enforcement officer, and thus has only 1 illegal paraphernalia in the evidence locker. John’s law-breaking activities are a little more successful, so he has 10 illegal paraphernalia. Let's imagine how this might look in an Edgeworth Box.
