Practice makes perfect
a Let's write the conditional statement, p→ q.
If you go to the zoo to see a lion, then you will see a cat. As explained in the exercise, this is a true conditional statement. The truth table for a true conditional statement looks like below.

p q p→ q
T T T
T F F
F T T
F F T
b Let's write the conditional statement, p→ q.
If you play a sport, then you wear a helmet. As explained in the exercise, this is a false conditional statement. However, since some sports require helmets, it is also false to say that you do not wear a helmet if you play a sport. Similarly, not playing a sport neither requires or exempts you from wearing a helmet. With this information we can write the following truth table.

p q p→ q
T T F
T F F
F T F
F F F
c Let's write the conditional statement, p→ q.
If this month has 31 days, then it is not February. As explained in the exercise, this is a true conditional statement. The truth table for a true conditional statement looks like below.

p q p→ q
T T T
T F F
F T T
