A)
(A U B)` infers a set that complements (A U B), i.e. a set of elements that don't exist in (A U B) and this is given as (5, 7, 9)
B)
Firstly, we establish the set (B U C) and find out elements that are common with A to get
A n (B U C)
A = (1, 2, 3, 4, 8)
(B U C) = (2, 4, 6, 7, 8, 9, 10)
Therefore, A n (B U C) = (2, 4, 8) | This is corroborated by our Venn Diagram.
