Answer from cs61c-cd (Charles Leung 15905350) for Question 3
I used four ands and an or to create this boolean expression.  We will need 7 wires in order to implement this circuit design.  I think 7 is correct because in my dsign i needed 7 different wires to hook up the iniput signals to the ANDs and OR.  We don't need wires for the inputs but we need wires to hook up the logic operators.
