1. The problem involves shading regions in Venn diagrams for sets A and B. 2. For part a, we need to shade set B. This means shading all elements that belong to B, including the intersection with A. 3. For part b, we need to shade the complement of A, denoted as $A'$. This means shading all elements not in A, which includes the region outside A but inside B and outside both. 4. In the Venn diagram, the regions are labeled as follows: - $a$: elements only in A - $b$: elements in both A and B - $c$: elements only in B - $d$: elements outside both A and B 5. For part a (shade B): shade regions $b$ and $c$. 6. For part b (shade $A'$): shade regions $c$ and $d$. This completes the shading instructions for the Venn diagrams.
