Math Problem Statement

Complete the truth table for ∼(p ↔ q)

Solution

It looks like you are working on a truth table for the logical statement (pq)\sim (p \leftrightarrow q), where \leftrightarrow represents the biconditional (if and only if). Let's walk through the steps to complete this truth table.

The logical expression (pq)\sim (p \leftrightarrow q) can be broken down as follows:

  1. Biconditional pqp \leftrightarrow q: This is true when both pp and qq have the same truth values (either both true or both false). Otherwise, it is false.
  2. Negation (pq)\sim (p \leftrightarrow q): After calculating pqp \leftrightarrow q, you negate the result. If pqp \leftrightarrow q is true, the negation is false, and if it's false, the negation is true.

Now, let's fill in the truth table based on the standard input values for pp and qq:

ppqqpqp \leftrightarrow q(pq)\sim (p \leftrightarrow q)
TTTF
TFFT
FTFT
FFTF
  • For p=Tp = T and q=Tq = T, pqp \leftrightarrow q is true, so (pq)\sim (p \leftrightarrow q) is false.
  • For p=Tp = T and q=Fq = F, pqp \leftrightarrow q is false, so (pq)\sim (p \leftrightarrow q) is true.
  • For p=Fp = F and q=Tq = T, pqp \leftrightarrow q is false, so (pq)\sim (p \leftrightarrow q) is true.
  • For p=Fp = F and q=Fq = F, pqp \leftrightarrow q is true, so (pq)\sim (p \leftrightarrow q) is false.

Make sure to fill in these values on your homework page, and this should complete the table correctly.

Here are 5 related questions for you:

  1. What is the difference between the biconditional (\leftrightarrow) and conditional (\rightarrow) operators?
  2. How does negation (\sim) affect the truth value of a statement?
  3. Can you construct a truth table for pqp \rightarrow q?
  4. What is the logical equivalence of pqp \leftrightarrow q in terms of conjunction (\land) and disjunction (\lor)?
  5. How would the truth table change if the expression was (pq)\sim(p \lor q) instead?

Tip: When creating truth tables, always start by computing the inner expressions and gradually build toward the final result.
