What could you say so that you can be sure to receive both Super Bowl tickets from John?

I'd say....Getter_dones toilet is as black as a clowns pocket.......

Oh ok.

I'd say....Getter_dones toilet is as black as a clowns pocket.......

If you said "Oh ok" to John, this not a statement that is true or false, so it is certainly not a true statement that would guarantee you both tickets.



Let's suppose for the sake of argument Getter-done's toiletisas black as a clowns pocket. Does this mean he gives you the 2 tickets?

It appears a correct answer has not yet been given.

What about my answer?

"You won't give me 1 ticket."

You will give me either zero or two tickets.

Yes this works. Wincel got it. Well done

What is true cannot be false. But if our eyes are false then what does that make mirrors.

You will need the vaccine to attend the Super Bowl

Journey to Knight and Knave Island:

On this island people are either knights who always tell true statements, or knaves who always tell false ones (Im sure you've seen these problems before). If some random guy comes up to you and says "Im a knight", you cannot be sure if its a knight telling the truth or a knave saying a falsehood. If someone says a square has 5 sides, he must be a knave, etc.

Question 1
Two guys come up to you and one says "We are both knaves". What are they?

Knave and Knight.
Proof:
Knight would say he is a knight. The speaker is a knave.
The other must be a knight to make the statement false.

Question 2
Two guys come up to you and one says "We are different types and he is a knight". What are they?

Both knaves.
Proof:
A knight would not be able to say they are different, and the other is a knight. The speaker must be a knave.
The other being a knight would make the knave honest. The other must be a knave.

Question 3(medium)
You come up to a fork in the road that splits two ways, and one way leads to the palace, but you dont know which way it is. An inhabitant of the island is standing by the fork, and you dont know if he is a knight or knave. What single question can you ask him, with a yes or no answer, that will tell you by his answer which path is the correct path to the palace?

Would the opposite form to yourself (knight/knave) tell me the left path leads to the palace?

Proof:
Knight would say, "yes," if it does not, "no" if it does.
Knave would lie "yes" if it does not because he cannot say the truth, "no".
The knave would lie "no" if the left path does lead to the palace because he cannot tell you the truth of "yes".






Question 4(hard)
Make up a question that a knight could answer yes, but not no, and that a knave could not answer at all*.

Are you telling the truth?
Question 5(hard)
Make up a question that neither a knight nor a knave could answer at all*.

*: and not because ofinsufficient information. In other words, you cant hold a playing card face down which the individual hasnt seen, and ask "is this card a red?"

What would the opposite of yourself (knight/knave) say is the correct path to the castle?

Unrelated to knights and knaves, but this question unlocks the key to infinity.
Question 6

There is an infinite line of boxes, starting with Box 1. So the line looks like Box 1, Box 2, Box 3, Box 4, Box 5,........ each box has a different set of positive whole numbers in it. So we might have something like:

Box 1: {3,6,8,9}
Box 2: The set of all positive even whole numbers
Box 3: {1,4}
Box 4: The set of all positive whole numbers less than 10
Box 5: {3837,888}
....
etc

We dont know what's in the specific boxes in front of you, that is just an example. In the general case, given a line of numbered boxes in front of you (Box 1,2,3,4,5......, each contains a different set of positive integers), can you name a set of positive whole numbers that is not inside any of the boxes?
