Vedclass · Answer

Contrapositive of $\mathrm{p} ightarrow \mathrm{q}$ is $\sim \mathrm{q} ightarrow \sim \mathrm{p}$

$(\mathrm{A} \subseteq \mathrm{B}) \Lambda(\mathrm{B} \subseteq \mathrm{D}) \longrightarrow(\mathrm{A} \subseteq \mathrm{C})$

Contrapositive is

$\sim(\mathrm{A} \subseteq \mathrm{C}) \longrightarrow \sim(\mathrm{A} \subseteq \mathrm{B}) \vee \sim(\mathrm{B} \subseteq \mathrm{D})$

$\mathrm{A} 
eq \mathrm{C} ightarrow(\mathrm{A} 
eq \mathrm{B}) \vee(\mathrm{B} 
eq \mathrm{D})$
