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
