Math Problem Statement

Is this correct

Is the truth table for p -> ~q correct?

Solution

Let's analyze the truth table to check if it is correct for the given logical statement p¬qp \rightarrow \neg q (read as "if pp, then not qq").

Here’s how we approach the problem:

  1. Given Statement: p¬qp \rightarrow \neg q

  2. Negation of qq (¬q\neg q):

    • q=Tq = T, then ¬q=F\neg q = F
    • q=Fq = F, then ¬q=T\neg q = T
  3. Implication p¬qp \rightarrow \neg q:

    • Implication p¬qp \rightarrow \neg q is false only if p=Tp = T and ¬q=F\neg q = F (i.e., p=Tp = T and q=Tq = T). Otherwise, it is true.

Now, let's check the table:

ppqq¬q\neg qp¬qp \rightarrow \neg q

Comparison with the provided table:

The table you uploaded shows:

ppqqp¬qp \rightarrow \neg q
TTF
TFT
FTT
FFT

It matches the correct truth table for p¬qp \rightarrow \neg q, so yes, the truth table is correct.

Would you like more details on truth tables or implications? Here are some related questions:

  1. How does the implication pqp \rightarrow q work logically?
  2. What happens if both pp and qq are false in an implication?
  3. Can you explain the difference between pqp \rightarrow q and qpq \rightarrow p?
  4. What is the significance of the negation ¬q\neg q in logical statements?
  5. How would a truth table look for the expression ¬(pq)\neg (p \wedge q)?

Tip: In logic, an implication is only false when the first part is true, and the second part is false.
