Question:
If A = {a, b, c, d, e}, B = {a, c, e, g} and C = {b, e, f, g}, find:
(i) $A \cap(B-C)$
(ii) $A-(B \cup C)$
(iii) $A-(B \cap C)$
Solution:
Given; A = {a, b, c, d, e}, B = {a, c, e, g} and C = {b, e, f, g}
(i) $A \cap(B-C)=\{a, c\}$
(ii) $A-(B \cup C)=\{d\}$
(iii) $A-(B \cap C)=\{a, b, c, d\}$
