$\overline{B \cup C}=\left\{0, 5, 9\right\}$
RECALL: (1) $\overline{C}$ is the complement of set $C$, which is the set that contains the elements of the universal set that are not elements of $C$. (2) $\cup$ represents the union of two sets, which is the set that contains the combined elements of the two given sets. Use (2) above to obtain: $B \cup C=\left\{1, 2, 3, 4, 6, 7, 8\right\}$ Use rule (1) above to obtain: $\overline{B \cup C}=\left\{0, 5, 9\right\}$
