To shade $\overline{B} \cap D$ on the Venn diagram:

1. Understand $\overline{B} \cap D$:

   • $\overline{B}$: This represents the region outside of set $B$.
   • $D$: This represents the region inside set $D$.
   • $\overline{B} \cap D$: This is the overlap between the region outside $B$ and inside $D$.

2. Determine the area to shade:

   • Look for the part of circle $D$ that does not overlap with circle $B$.

3. Shade the appropriate area:

   • Shade only the part of circle $D$ that is outside circle $B$, as that represents $\overline{B} \cap D$.
