Without knowing the exact way your text defines statement it hard to judge the I above. For example some would say the 4 is an X because it in neither true or false.I’ve answered
I. 1. P 2. X 3. P 4. P 5. P
II.
1. p^¬q 2. ¬p^¬q 3. q⇒(¬r)
but I’m unsure of these answers still
Without knowing the exact way your text defines statement it hard to judge the I above. For example some would say the 4 is an X because it in neither true or false.
In II I agree with 1. & 3. But for 2. \(\neg(p\wedge q)\).
As you should, this is the implication truth table:
\(\begin{array}{*{20}{c}}
p&q&{p \to q} \\ \hline t&t&t \\ t&f&f \\ f&t&t \\ f&f&t \end{array}\)
By looking at that table, consider these two statements.
A true statement is implied by any statement.
A false statement implies any statement.
\(\begin{array}{*{20}{c}} p&q&r&{p \to q}&{\neg p \to r}&{(p \to q) \vee (\neg p \to r)} \\ \hlineThis is my answer to some, not yet done tho
