      wooo.... my favourite...

      first one:
      the output is only zero if and only if
      Case 1: X=0 and Y=1
      Case 2: X=1 and Z=1

      so, all with 01x or 1x1 where x can be 0 or 1, will be zeros. The rest will give you ones

      000      1
      001      1
      010      0
      011      0
      100      1
      101      0
      110      1
      111      0

       

       

      2nd question:

      1st one: B*C + A*C'
      2nd one: A+C
