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