# Four Card Monte

The face cards of a deck of red-backed playing cards and blue-backed playing cards are shuffled together. Then they are cut, one side is turned face up and they are shuffled together face-up and face-down. Then four cards are dealt out on the table like this:

Red Blue King Jack

How many cards must you turn over to correctly answer the question:

"Does each red card on the table have a jack on the other side?"

You must choose all of the cards to be flipped before any of them are flipped.

what are you talking about

Excellent puzzle. I knew I was wrong about the Jack but I was too impatient to figure out why.

At the same time, you don't need to flip over the king. Because if it were a red card or not the answer would be the same. Yes or no.

sorry - only if you consider the Jack at the end to be "next to" the red card on the opposite side.

the CORRECT answer is 3. its 3 because u need to see if the red card is a jack, if the king is a red card, and if the jack is a red card.

Sorry, ultima, but the answer given is correct. It doesn't matter what color the jack is. Think of it this way: if there were five jacks on the table, all face up, would you have to flip ANY of them over to answer the question? Nope. All of the red cards would definitely be jacks. The jacks that happen to be blue would not change the answer.
