Construct a Truth Table for the given statement:
1. p implies ~(pVq)
2. ~(p AND q)Vp
I thought this is how to do it, but my teacher marked it incorrect:
1. p q ~(pVq) p implies ~(pVq)
T T F T implies T= T
T F F T implies F= F
F T F F implies F= T
F F T F implies T= T
2. p q ~(p AND q) ~(p AND q)Vp
T T F FVT= T
T F T TVT= T
F T T TVF= T
F F T TVF= T
Show me what and how I did this wrong? Did forget a column? Please show me everything that is wrong.
Thank you so much.
Based on the given expressions, let's go through each step to construct the truth tables correctly.
1. Truth Table for p implies ~(pVq):
To find the truth values for this statement, we need to evaluate the individual parts before the implication.
1.1 Evaluate ~(pVq):
p q pVq ~(pVq)
---------------------
T T T F
T F T F
F T T F
F F F T
1.2 Evaluate p implies ~(pVq):
Now that we have the truth values for ~(pVq), we can evaluate the overall statement.
p q ~(pVq) p implies ~(pVq)
---------------------------------
T T F T
T F F F
F T F T
F F T T
Your table for the first statement is correct.
2. Truth Table for ~(p AND q) V p:
To find the truth values for this expression, we'll evaluate the individual parts before the OR operation.
2.1 Evaluate ~(p AND q):
p q p AND q ~(p AND q)
-----------------------------
T T T F
T F F T
F T F T
F F F T
2.2 Evaluate ~(p AND q) V p:
Now that we have the truth values for ~(p AND q), we can evaluate the overall statement.
p q ~(p AND q) ~(p AND q) V p
-----------------------------------
T T F T
T F T T
F T T F
F F T F
Your table for the second statement is also correct.
In conclusion, your truth tables for both statements are correct. It seems that there might have been a mistake in grading.
