you want an expression which is 1 ONLY when w = x = 0, y = z = 1, and for no other possible values of w,x,y,z.
furthermore, if this is only to be a conjunction terms like yz aren't allowed, so what you want is:
~w & ~x & y & z
Find the fundamental conjunction made up from the variables w, x, y, z, or their complements, where the value of the conjunction is 1 precisely when:
w=x=0, y=z=1
So is this question asking us to find an equation that would equal 1 and at the same time use (in this question) w=x=0 and y=z=1?
Would notX(y)+ yz work? notx(y)= 1(1) and y(z)= 1(1) 1+1=1
