Question

If p is false and q is true, then

• A. $p\wedge q$ is true
• B. $p\vee \sim q$ is true
• C. $q\wedge p$ is true
• D. $p\Rightarrow q$ is true

Answer 1

Answer: (D)

When p is false and q is true, then $p\wedge q$ is false,$p\vee \sim q$ is false,
($\because$ both p and $\sim q$ are false)
and $q\Rightarrow p$ is also false,
only $p\Rightarrow q$ is true.
