What is the logical representation of the statement: Unless we want a disaster on our hands and the holidays ruined, we will have to not both let your mother and your father come this Christmas?

~ (M v F) (V ~D)

D H -> (M v F)

~(D H) -> (M v F)

(D H) v ~ (M F) (correct)

Study Notes

Symbolization Quizzes Overview

The quizzes explore logical symbolization using letters and symbols to represent statements clearly.
Familiarity with logical operators is essential for effective symbolization.

Card Summaries

Card 1: The condition for avoiding disaster entails not inviting both parents: (D ∧ H) v ~(M ∧ F).
Card 2: To prevent disaster, at least one parent must not be invited: ~(D ∧ H) → (~M v ~F).
Card 3: Inviting neither parent leads to a vacation without disasters: ~(M v F) ∧ (V ∧ ~D).
Card 4: A peaceful Christmas is contingent upon not inviting either parent: C → ~(M v F).
Card 5: Beach trip possible if everyone gets vacation time and an affordable condo: B → (V ∧ C).
Card 6: Cooking is necessary if no restaurant or takeout option is available: ~(R v T) → C.
Card 7: Harry and John getting green pants excludes Michael from getting them: (H ∧ J) → ~M.
Card 8: Fordham's course expansion ties to Georgetown’s endowment affecting Duke's tuition and Tulane's class size: F → [G → (D ∧ T)].
Card 9: Both Harry and John enjoy banana bread while Michael does not: (H ∧ J) ∧ ~M.
Card 10: Williams' enrollment increase prevents both Fordham and Georgetown from expanding course offerings: W → ~(F ∧ G).
Card 11: New scholarships from Williams are contingent on Amherst's class size or Smith not hiring faculty: W ↔ (A v ~S).
Card 12: Given formula is a well-formed formula (wff); main operator is the first implication: [(P ∧ Q) ∼Q] → (P → R).
Card 13: The first formula is a wff, needing main operator identification; second formula is also a wff, focuses on logical connections.
Card 14: The last formula fails to be a wff, indicating a structural issue in logical formation: ~[(R ∧ S) → U] → {{~U → [R → (S → T)]}.

Key Logical Concepts

Understanding wffs (well-formed formulas) is critical in logical analysis.
The representation of statements using symbols facilitates complex reasoning.
Operators such as conjunction (∧), disjunction (v), and implication (→) form the foundation of logical reasoning.
