Assuming that you mean not (p or q) if and only if P ~(PVQ)--> P so now construct a truth table, (just place it vertical since i cannot place it vertical through here.) P True True False False Q True False True False (PVQ) True True True False ~(PVQ) False False False True ~(PVQ)-->P True True True False if it's ~(P^Q) -->P then it's, P True True False False Q True False True False (P^Q) True False False False ~(P^Q) False True True True ~(P^Q)-->P True True False False
False.
Neither. It is a hypothesis which may be true until proved or proved to be false.
Yes, it is true.
For Apex the answer is “True“.
True. A valid argument can have a false conclusion if the premises logically lead to that conclusion even though it is not true. Validity in logic refers to the structure of the argument, regardless of the truth or falsity of the premises or conclusion.
False. Not all laws made by a government are considered valid. Laws must adhere to the constitution and legal principles to be considered valid and enforceable. Additionally, laws that violate basic human rights or are unconstitutional can be challenged and overturned.
Facts cannot be valid. They can only be true or false. Arguments, on the other hand, can be valid. A valid argument in one which must have a true conclusion provided that the premises are true (no guarantee of that though).
true or false
If you mean edges, true. If you mean faces, false.
A sound argument cannot have a false conclusion. A sound argument refers to a deductive argument which is valid and has all true premises, therefore its conclusion cannot be false.
True
True.
It means 'true'.
No, valid arguments can have false conclusions. Validity refers to the logical connection between the premises and the conclusion, ensuring that if the premises are true, then the conclusion must also be true. However, the validity of an argument does not guarantee the truth of the conclusion, as the premises themselves could be false.
The premises in syllogisms can be true or false, depending on the accuracy of the statements. The validity of a syllogism is determined by the logical structure of the argument, not just the truth of the premises.
When someone calls a statement a "valid assumption" they mean that it is probably true.
