Let's calculate each of the answer choices and see which one DOES NOT equal $36$. $A$ comes out to be $-4\times -9=36$, $B$ equals $-3\times -12=36$, $C$ is $\frac{1}{2}\times -72=-36$, $D$ simplifies to $1\times 36=36$, and $E$ equals $\frac{3}{2}\times 24=3\times 12=36$. Thus, our answer is $\boxed{\{\frac{1}{2},-72\}}$.
