Solution

To construct the truth table for the compound statement pq\sim p \lor q, let's calculate each column step by step.

Truth Table Layout

The table has the columns:

  1. pp (truth value of the first variable)
  2. qq (truth value of the second variable)
  3. p\sim p (negation of pp)
  4. pq\sim p \lor q (logical OR between p\sim p and qq)

Truth Table Construction

ppqqp\sim ppq\sim p \lor q
TTFT
TFFF
FTTT
FFTT

Step-by-Step Explanation

  1. Column pp and qq: The truth values of pp and qq are taken as all possible combinations of TT and FF (true and false). There are four combinations: (T,T),(T,F),(F,T),(F,F)(T, T), (T, F), (F, T), (F, F).
  2. Column p\sim p: Negate the values of pp. If p=Tp = T, then p=F\sim p = F; if p=Fp = F, then p=T\sim p = T.
  3. Column pq\sim p \lor q: Apply the logical OR (\lor) operation between p\sim p and qq. Logical OR is true if at least one operand is true:
    • FT=TF \lor T = T
    • FF=FF \lor F = F
    • TT=TT \lor T = T
    • TF=TT \lor F = T

Do you want a more detailed explanation of how logical OR works or any part of the table? Here are related questions:

  1. What does the symbol \lor represent in logic?
  2. How is the negation p\sim p calculated?
  3. What are the basic truth table rules for \lor (OR)?
  4. Can you provide an example with different variables to practice this?
  5. How does this relate to circuits in digital logic?

Tip: For compound logical statements, build the table incrementally to avoid errors!
