1. Simplify the following with Identities and K-Maps: xy~z + ~x~yz + yz
2. Which of the following is NOT logically equivalent to the rest:
   1. wx~y + w~z + wxyz + w~yz
   2. w(x + ~y + ~z)
   3. w + x + ~y + ~z
   4. wx + w~y + w~z
3. Use K-Maps to simplify each of the following:
   1. ~x~y~z + ~xyz + ~xy~z
   2. ~x~y~z + ~xy~z + x~y~z + xy~z
   3. ~y~z + ~yz + xy~z
