Answer 1

Answer:

As the quantity demanded for good A increases, so does the demand for good B. On the flip side, as less people want good A, the demand for good B will also go down.

Answer 2

Answer:

i) Complement Laws: The union of a set A and its complement A' gives the universal set U of which, A and A' are a subset. A ∪ A' = U. Also, the intersection of a set A and its complement A' gives the empty set ∅. A ∩ A' = ∅ For Example: If U = {1 , 2 , 3 , 4 , 5 } and A = {1 , 2 , 3 } then A' = {4 , 5}.
