Solution
Solution Steps
Step 1: Define the propositions
p: You got a flu shot.
q: You got the flu.
Step 2: Determine the truth values of p and q
Since the problem states "You got a flu shot" and "you got the flu," both p and q are true.
Step 3: Evaluate the truth value of ¬p → ¬ q
¬p: You did not get a flu shot (False)
¬q: You did not get the flu (False)
¬p → ¬q: If you did not get a flu shot, then you did not get the flu. (True)
A conditional statement is only false when the hypothesis is true, and the conclusion is false.
Final Answer:
| p | q | ¬p | ¬q | ¬p → ¬q |
|---|---|---|---|---|
| T | T | F | F | T |
