Use a truth table to answer the following question.Which, if any, set of truth values assigned to the atomic sentences shows that the following argument is invalid? ∼MM⊃N\frac { \sim \mathrm { M } } { \mathrm { M \supset N }}MNM

A) M: T N: T
B) M: T N: F
C) M: F N: T
D) M: F N: F
E) None-the argument is valid.

Atomic Sentences

The simplest type of sentences in logic, containing no logical connectives and expressing a complete thought.

Truth Values

Represent the valuation in logic that indicates the truthfulness of a statement, typically classified as true or false.

Truth Table

A table in logic that calculates the outputs of logical expressions, taking into account each of their functional arguments.

  • Develop an understanding of valid argument constructs.
  • Accomplish expertise in constructing and interpreting truth tables.
  • Engage with the notion of logical negation and assess its repercussions on the legitimacy of discourse.

Final Answer :
E
Explanation :
An argument is invalid if it's possible for the premises to be true while the conclusion is false. In this case, the premise is ∼M\sim MM (not M), and the conclusion is M⊃NM \supset NMN (if M then N). For the argument to be invalid, we would need a situation where ∼M\sim MM is true, but M⊃NM \supset NMN is false. However, M⊃NM \supset NMN is only false when M is true and N is false. Since the premise ∼M\sim MM means M is false, there's no situation where the premise is true and the conclusion is false, making the argument valid.
