Let $\displaystyle U$ be the universal set, $\displaystyle A$ and $\displaystyle B$ are the subsets of $\displaystyle U$. If $\displaystyle n(U) = 650$, $\displaystyle n(A) = 310$ $\displaystyle n(A \cap B) = 95$ and $\displaystyle n(B) = 190$, then $\displaystyle n(A \cap B)^c$ is equal to ($\displaystyle A$ and $\displaystyle B$ are the complement of $\displaystyle A$ and $\displaystyle B$ respectively):
