Q94
Set down the relation between universal and existential quantification by matching the List I with List II and select the appropriate answer: List-I List-II a. [(X) ϕX] 1. ≡ [∼ (X) ϕX] b. [(∃x) ϕX] 2. ≡ [∼ (∃x) ϕX] c. [(X) ∼ ϕX] 3. ≡ [∼ (X) ∼ ϕX] d. [(∃x) ∼ ϕX] 4. ≡ [∼ (∃x) ∼ ϕX]
Set down the relation between universal and existential quantification by matching the List I with List II and select the appropriate answer:
| List-I | List-II |
| a. [(X) ϕX] | 1. ≡ [∼ (X) ϕX] |
| b. [(∃x) ϕX] | 2. ≡ [∼ (∃x) ϕX] |
| c. [(X) ∼ ϕX] | 3. ≡ [∼ (X) ∼ ϕX] |
| d. [(∃x) ∼ ϕX] | 4. ≡ [∼ (∃x) ∼ ϕX] |
