To sketch: A Venn diagram and shade the section

Answer to Problem 2TTO
A required Venn diagram as shown below.
Explanation of Solution
Step 1:
Draw a Venn diagram and name each area with a Roman numeral.
Step 2:
From the Venn diagram, list the regions that make up each set.
Step 3:
Compute
The regions I and II are in
Therefore, the regions III and IV are not in A.
That is, the complement of A is III and IV.
That is,
The region II, III and IV are in either
That is,
Step 4:
By step 3, shade the region II, III and IV as shown in below Figure 2.
From the Figure 2, it is observed that shaded regions represents
