a) Determine fundamental conjunction made up from variables w, x, y, z, or their complements, where value of conjunction is 1 precisely when
i) w = x = 0, y = z = 1.
ii) w = 0, x = 1, y = 1, z = 0.
iii) w = 0, x = y = z = 1.
iv) w = x = y = z = 0.
b) Answer part (a) for fundamental disjunctions, instead of fundamental conjunctions, where value of every fundamental disjunction is 0 precisely for stated values of w, x, y, z.
