Question:

If A = {a, b, c, d, e, f}, B = {c, e, g, h} and C = {a, e, m, n}, find:

(i) $A \cup B$

(ii) $\mathrm{B} \cup \mathrm{C}$

(iii) $B \cup C$

(iv) $\mathrm{C} \cap \mathrm{A}$

(vi) $A \cap B$

Solution:

Given; A = {a, b, c, d, e, f}, B = {c, e, g, h} and C = {a, e, m, n}

(i) $A \cup B=\{a, b, c, d, e, f, g, h\}$

(ii) $B \cup C=\{a, c, e, g, h, m, n\}$

(iii) $B \cup C=\{a, c, e, g, h, m, n\}$

(iv) $C \cap A=\{a, e\}$

(vi) $A \cap B=\{c, e\}$
