Question 1: Venn Diagram for [(A ⋂ B)' - C] ⋂ [(A + B) - C]
To solve this, let's break down the expression step by step and draw the Venn
diagrams accordingly:
1. [(A ⋂ B)' - C]:
o First, find the complement of A∩BA \cap BA∩B: This is everything
outside A∩BA \cap BA∩B.
o Subtract CCC from this complement.
2. [(A + B) - C]:
o Find A+BA + BA+B, which is A∪BA \cup BA∪B.
o Subtract CCC from A∪BA \cup BA∪B.
Combining these two results using intersection gives us the desired set.
Since I don't have the Venn diagrams to choose from (options a, b, c, d), you
would need to refer to those to identify which diagram correctly represents the
set.
Question 2: Counterexample for (A - B) U C' = (C' - B) + A
To find a counterexample:
 Substitute each given set of A,B,A, B,A,B, and CCC into both sides of
the equation.
 Check if both sides are equal for any given set. If they are not equal for
one set, that set is a valid counterexample.
Let's go through the options:
 Option a: A = {1}, B = {2}, C = {3}
 Option b: A = {1}, B = {1}, C = {2}
 Option c: A = {1, 2}, B = {1, 2}, C = {3}
 Option d: A = {3}, B = {3, 4}, C = {4}
Substitute these into the equation to find the counterexample.
