4. Complete the truth table for a system with 3 inputs, a, b, and c, and 4 outputs, w, X, Y, Z. The output is a binary number equal to the smallest integer that meets the input conditions: a = 0: odd a = 1: even b = 0: prime b = 1: not prime c= 0: less than 8 c= 1: greater than or equal to 8 Some inputs may never occur; the output is never all O's. (A prime is a number that is only evenly divisible by itself and 1.) To be sure you understand the problem, I have completed one output row. a b W Z 0 0 0 0 0 1 0 1 0 x x x 0 1 1 1 0 0 1 0 1 1 1 0 1 1 1
