அடுக்கு கணங்கள்

$(i) \quad A=\{a, b\} \\ P(A)=\{\{a\},\{b\},\{a, b\},\{\}\}$

$\begin{aligned}&\text { (ii) } \mathrm{B}=\{1,2,3\}\\&P(B)=\{\{1\},\{2\},\{3\},\{1,2\},\{2,3\},[1,3\},\{1,2,3\},\{\}\}\end{aligned}$

$\text { (iii) } \mathrm{D}=\{\mathrm{p}, \mathrm{q}, \mathrm{r}, \mathrm{s}\}$

$\begin{aligned}&\begin{array}{l}\mathrm{P}(\mathrm{D})=\{\{\mathrm{p}\},\{\mathrm{q}\},\{\mathrm{r}\},\{\mathrm{s}\},\{\mathrm{p}, \mathrm{q}\},\{\mathrm{p}, \mathrm{r}\} \{\mathrm{p}, \mathrm{s}\},\{\mathrm{q}, \mathrm{r}\},\{\mathrm{q}, \mathrm{s}\},{\mathrm{r}, \mathrm{s}\},\{\mathrm{p}, \mathrm{q}, \mathrm{r}\},\{\mathrm{p}, \mathrm{q}, \mathrm{s}\}\end{array}\\&\{q, r, s\},\{p, r, s\},\{p, q, r, s\},\{\}\}\end{aligned}$

$\text {( iv) } \mathrm{E}=\phi$

$P(E)=\{\}=\phi$
