    outputs consisting of 3 bits

    How many different outputs consisting of 3 bits can be made from 5 different inputs?


    thanks for helping!

    As far as I am concerned, this phrasing of your question is not sufficiently clear. In the context of what kind of input-output system are you asking this question? If it's a static arrangement of logic gates, then there can only be 2^3=8 different outputs anyway, and to bring them about, 5 different inputs are certainly sufficient.
    But you could be taking about a more general kind of input-output automaton. - If so, what kind?
