Question

shade the area or areas of the venn diagram that represent $(a cup b)$.

Explanation:

Step1: Define the union $A \cup B$

$A \cup B$ is all elements in circle $A$, circle $B$, or both.

Step2: Define the complement $(A \cup B)'$

$(A \cup B)'$ is all elements in the universal set $U$ not in $A \cup B$, which is the region outside both circles.

Answer:

Shade the region of the universal set $U$ that is outside both circle $A$ and circle $B$ (containing the numbers 2, 1, and 17).
