Famous Probability Puzzle

This is a famous probability puzzle in which you have to choose the correct answer at random from the four options below. Can you tell us whats the probability of choosing correct answer in this random manner. 1) 1/4 2) 1/2 3) 1 4) 1/4


There is no correct answer. probability of choosing correct answer is 0.


1) why cant be 1/4 : If the answer is 1/4, then as we know two out of four answer choices is '1/4', the answer has be 1/2.
This is a contradiction, so the answer cannot be 1/4.

2) why cant be 1/2 : If the answer is 1/2 then because answer:"1/2" is 1 out of 4 answer choices, the answer must be 1/4. This is also a contradiction. So the answer cannot be 1/2.

3) why cant be 1 : If the answer is 1 then because answer:"1" is 1 out of 4 answer choices, the answer must be 1/4. Again the same contradiction and therefore answer cannot be 1.
