Here is a quick tutorial on two different truth tables.
If there's anyone wondering about the "IF/THEN" statements (the one way arrows), please read below:
Think about the statement "If you get an A on your exam, then I will give you $100". This statement will only be False if I break my promise to you.
Therefore:
- If it's TRUE (you got an A), and it's TRUE (I gave you $100), then it's TRUE (I kept my promise).
- If it's TRUE (you got an A), and it's FALSE (I didn't give you $100), then it's FALSE (I broke my promise).
- If it's FALSE (you didn't get an A), and it's TRUE (I gave you $100), then it's TRUE (I didn't break my promise, I was just feeling sorry for you and felt like being generous).
- If it's FALSE (you didn't get an A), and it's FALSE (I didn't give you $100), then it's TRUE (I kept my promise, you didn't earn the $100 from me)!
