An AND gate logic device has six input lines. How many combinations of ones and zeros produce a one-level output? How many combinations will produce a zero-output from the device?

What will be an ideal response?


Six inputs provide 2^6 = 64 input combinations. Since an AND gate produces
a one-level output when all inputs are one, only one input combination
(111111) provides the high output. The remaining 63 combinations all have
at least one 0 and produce a zero output.
