If p then q is represented as p -> q Negation of "if p then q" is represented as ~(p -> q)
what is the correct truth table for p V -q?
what is the correct truth table for p V~ q
what is the correct truth table for -p-> -q?
A+
P-q and q-p are logically equivalent prove?
p --> q and q --> p are not equivalent p --> q and q --> (not)p are equivalent The truth table shows this. pq p --> q q -->(not)p f f t t f t t t t f f f t t t t
Where p and q are statements p and q is called what of p and q?
The truth values.
Construct a truth table for p and q if and only if not q?
Construct a truth table for ~q (p q)

What is the truth table for p and negation q?
P | T T F F Q | T F T F Q' | F T F T P + Q' | F T F F The layout is the best I could do with this software. Hope it is OK.

Make a truth table for the statement if p then not q?
. p . . . . . q. 0 . . . . . 1. 1 . . . . . 0
What is the truth table for p arrow q?
Not sure I can do a table here but: P True, Q True then P -> Q True P True, Q False then P -> Q False P False, Q True then P -> Q True P False, Q False then P -> Q True It is the same as not(P) OR Q
What is the proof of the modus ponens not by the truth table?
1)p->q 2)not p or q 3)p 4)not p and p or q 5)contrudiction or q 6)q
Is The inverse is the negation of the converse?
No, the inverse is not the negation of the converse. Actually, that is contrapositive you are referring to. The inverse is the negation of the conditional statement. For instance:P → Q~P → ~Q where ~ is the negation symbol of the sentence symbols.
What notation does a condition statement use?
"if p then q" is denoted as p → q. ~p denotes negation of p. So inverse of above statement is ~p → ~q, and contrapositive is ~q →~p. ˄ denotes 'and' ˅ denotes 'or'
What is the truth table for p or q and the opposite of p and q?
