NAND is false when...
Choose one option.
Show answer
- C. P and Q are true
Explanation
NAND is false only when \(P\) and \(Q\) are true, because then \(P\land Q\) is true and its negation is false.
Review the concept: NAND
Given propositions \(P\) and \(Q\), the NAND operation is the negation of their conjunction.
\[P\mathbin{\uparrow}Q=\neg(P\land Q)\]
