Math Problem Statement

Complete the truth table for the given proposition: p ⊕ (p ∨ q)

Solution

Let's go through the truth table in your image step by step to complete it.

The given expression is p(pq)p \oplus (p \lor q), where:

  • pqp \oplus q represents the exclusive OR (XOR), which is true if either pp or qq is true, but not both.
  • pqp \lor q is the logical OR, which is true if at least one of pp or qq is true.

You have the following partial truth table:

ppqqpqp \lor qp(pq)p \oplus (p \lor q)
TTT?
TFT?
FTT?
FFF?

Step 1: Complete pqp \lor q (already done in the table)

  • When p=Tp = T and q=Tq = T, pq=Tp \lor q = T.
  • When p=Tp = T and q=Fq = F, pq=Tp \lor q = T.
  • When p=Fp = F and q=Tq = T, pq=Tp \lor q = T.
  • When p=Fp = F and q=Fq = F, pq=Fp \lor q = F.

This part is already filled in the table.

Step 2: Calculate p(pq)p \oplus (p \lor q)

This is the XOR operation between pp and pqp \lor q.

  • p(pq)p \oplus (p \lor q) is true if pp and pqp \lor q have different truth values.
ppqqpqp \lor qp(pq)p \oplus (p \lor q)
TTTF
TFTF
FTTT
FFFF

Final Answer:

  • For p=Tp = T and q=Tq = T, p(pq)=Fp \oplus (p \lor q) = F.
  • For p=Tp = T and q=Fq = F, p(pq)=Fp \oplus (p \lor q) = F.
  • For p=Fp = F and q=Tq = T, p(pq)=Tp \oplus (p \lor q) = T.
  • For p=Fp = F and q=Fq = F, p(pq)=Fp \oplus (p \lor q) = F.

Here are five related questions to deepen your understanding:

  1. What is the difference between XOR and OR in truth tables?
  2. How would you build a truth table for pqp \land q (AND operation)?
  3. What does the logical equivalence pq¬(p    q)p \oplus q \equiv \neg(p \iff q) mean?
  4. How can you express pqp \oplus q using only AND, OR, and NOT operations?
  5. What are the common uses of XOR in digital logic design?

Tip: XOR is useful for detecting differences between two inputs, often used in error detection and correction algorithms!
