Question
[ NOT(p AND q) AND (NOT p OR q) AND (NOT q OR q) ] AND p
Question 4 Answers:
a. T
b. F
c. q
d. NOT q
e. None of the Given Choices
f. p
g. NOT p
Solution
Sure, let's break down the given expression step by step:
-
The expression is:
[ NOT(p AND q) AND (NOT p OR q) AND (NOT q OR q) ] AND p
-
Let's simplify each part inside the brackets first:
NOT(p AND q)
: This is the negation of the conjunction ofp
andq
. According to De Morgan's laws, this is equivalent toNOT p OR NOT q
.NOT p OR q
: This is already in its simplest form.NOT q OR q
: This is a tautology becauseq
ORNOT q
is always true.
-
Now, substitute the simplified parts back into the expression:
[ (NOT p OR NOT q) AND (NOT p OR q) AND true ] AND p
-
Since
true
does not affect the conjunction, we can simplify further:[ (NOT p OR NOT q) AND (NOT p OR q) ] AND p
-
Distribute the
AND
inside the brackets:[(NOT p OR NOT q) AND (NOT p OR q)]
-
Let's analyze the expression
(NOT p OR NOT q) AND (NOT p OR q)
:-
This can be simplified by considering the possible values of
p
andq
:- If
p
is true, thenNOT p
is false, so the expression depends onq
. - If
q
is true, thenNOT q
is false, so the expression depends onp
.
- If
-
The expression
(NOT p OR NOT q) AND (NOT p OR q)
simplifies toNOT p
.
-
-
Now, substitute back into the main expression:
[ NOT p ] AND p
-
This simplifies to:
NOT p AND p
-
NOT p AND p
is always false becausep
andNOT p
cannot be true at the same time.
Therefore, the answer is:
b. F.
