Q1: Consider the following sets $$ \begin{array}{1} \text { Set } \mathrm{A}=\{2,4,6,8,10,12\} \text { set } \mathrm{B}=\{3,6,9,12,15\} \text { set} \mathrm{C}=\{1,4,7,10,13,16\} \end{array} $$ Find: 1. $\mathrm{A} \cup \mathrm{B} $ 2. $\mathrm{A} \cap \mathrm{B} $ 3. $B \cap A$ 4. $B \cup A$ 5. B $\cup \mathrm{C} $ 6. Is $\mathrm{A} \cup \mathrm{B}=\mathrm{B} \cup \mathrm{A}$ ? 7. Is $\mathrm{B} \cap \mathrm{C}=\mathrm{B} \cup \mathrm{C}$ ? 8. $(A cup B) \cap(A \cup C)$ 9. $\mathrm{A} \cup(\mathrm{B} \cap \mathrm{C})$ 10. How many power sets $(\mathrm{PA})$ does set $\mathrm{A}$ have? Q2: If the set $c=\{a, c\}$ and set $b=\{d, v\}$ find the cartesian product cxb? Q3: write a correct $2$ notations to specify that a variable $x$ is a natural number such that $\mathrm{x} $ is greater that 7 and $\mathrm{x}$ is less that 100 ? CS. JG.024
