Find The Kind (Riddle/Brain Teaser)?

Question

You’re playing a card game entitled “Find the King”. 5 cards are on the table face down, 4 of them are Queen, and of course 1 King. You select card number 1, the dealer then flips 3 cards over and they are all Queens (card numbers 3,4,5). So you are now left with cards (1 and 2), He then says to you: ‘Do you want to switch to card number 2?’ Is it to your advantage to take the switch? And what is the probability card number 2 is the King?

I created this modified version of the Monty Hall some years back, to help others understand how to solve and understand these types of problems using Bayes's Theorem of Conditional Probabilities. I would give a more indepth answer but I have limited space.

carl is correct... switch to card number 2, it has 80% odds.

Answer 1

Switch, the odds of your card being a king is 20% so switching gives you an 80% chance.

Answer 2

NO! stick with the card u chose. Ur first guess is almost always right! Its a 50/50 chance

Answer 3

50/50

Answer 4

50% queen & 50% king

Answer 5

Number 10. The man who drives a toyota; because cats like to eat fish. That's why the guy moved next to him, so his cats can have food.

Answer 6

its a 50-50 chance you will get the king... your best off staying to what you picked

Answer 7

50%

Answer 8

I would say, switch. Why would whoever set it up put all four queens in a row?

Answer 9

Wow, I heard something like this on Numb3rs. I would stay with the one you have.

Answer 10
