    Conjunction / Disjunction Word Problem

    There are 12 balls on the top of the board, numbered left to right. There is a platform in front of you with buttons numbered 1-12 corresponding to the 12 balls. The goal is to push 6 buttons, releasing 6 balls, so that only one ball is allowed to reach the bottom. Using your knowledge of ANDs and ORs, which six balls should you release? (There is more than one answer).

    Re: Conjunction / Disjunction Word Problem

    If both balls end up in an and gate, does it release both balls, or just one of them?

    If it only releases one, then you could do 1,2,3,4,5,8
    If it releases both, I don't think you can do it. Because it would inevitably lead to at least 2 balls going in.
