Let p and q be statements. Identify the truth table for q → p.

Serjik [45]

Answer:

T F T T.

Step-by-step explanation:

Let p and q be two statement

When the value of p is true and the value of q is true then the value of $q\implies p$ is true.

When the value of p is true and the value of q is false then the value of $q\implies p$ is true.

When the value p is false and the value of q is true then the value of $q\implies p$ is false.

When the value of p is false and the value of q is false then the value of $q\implies p$ is true.

Hence, the value of $q\implies p$ is false when q is true and p is false.
