Question
Make up sets $A$ and $B$ such that $A \cup B$ has four elements and $A \cap B$ has four elements. Write your sets using the roster method.
Step 1
The union of two sets, A and B, denoted by A ∪ B, is the set of elements which are in A, in B, or in both A and B. The intersection of two sets, A and B, denoted by A ∩ B, is the set of all objects that are members of both A and B. Show more…

(a) If $A=\{1,2,3,4\}, B=\{2,4,5,8\}, C=\{3,4,5,6,7\}$, find (i) $B \cup C$, (ii) $A \cap B$, (iii) $A-C$. (b) Let $S=\{a, b, c, d, e\}$ be the Universal set and let $A=\{a, b, d\}$ and $B\{b, d, e\}$ be two of its subsets. Find $(A \cap B)^{\prime}$ and $(A \cup B)^{\prime}$.
