  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
