(b) For disjoint ordered sets P and Q define order 1.5 relation on \( P \cup Q \). Draw the diagram of ordered sets (i) \( 2^{2} \times 2 \) (ii) \( 3 \cup^{\text {is }} \overline{3} \) (iii) \( \mathrm{M}_{2} \stackrel{2}{\oplus} \mathrm{M}_{3} \) where \( M_{n}=1 \oplus \bar{n} \oplus 1 . \quad 7.5 \)
