Suppose that the universal set $\displaystyle {U}$ is the set defined as $\displaystyle {U}={\lbrace}$whole numbers $\displaystyle {\mid}$ the numbers greater than 5 and less than 15$\displaystyle {\rbrace}$.

Write the sets $\displaystyle {A}$ and $\displaystyle {B}$ out in roster notation.

$\displaystyle {C}={\lbrace}$a number in U $\displaystyle {\mid}$ the number is an odd number $\displaystyle {\rbrace}={\lbrace}$ $\displaystyle {\rbrace}$

$\displaystyle {D}={\lbrace}$a number in U $\displaystyle {\mid}$ the number is a composite number $\displaystyle {\rbrace}={\lbrace}$ $\displaystyle {\rbrace}$



Find each of the following:

$\displaystyle {n}{\left({C}\right)}=$

$\displaystyle {n}{\left({D}\right)}=$
