    Linked together how? Do you mean all parts have to work for the system to work, or is it more complicated?

    Well for a, 1, 2, and 3 have to work.
    For b 1 has to work or 2 and 3 have to work.
    For c 1 or 2 have to work and 3 has to work.

    Can you see how to write these statements in the language of probability?
