First comment! :lol: Great teaser, I got it simply because I read too many trick brain teasers. I saw the name in the new teasers section and luckily glanced at the category before answering. I thought it was probability at first. :D | |

I love your teasers! They're all very creative and and perfect in every way! :D | |

bwuuuuuuuuuuuh. I got it wrong and still don;t get it after reading the answer. That was extremely clever. | |

The correct answer is B. The question is phrased "IF you choose to answer this question at random." 50%! | |

Posted by kitty-cat | 11/28/12 |

But if the correct answer is B, then you DON'T have a 50% chance of getting it right. If the answer is 50%, then the answer is actually 25%, but then it would be 50, and it's an endless loop, a paradox. | |

:lol: Thank you kitty. | |

Okay, I see the paradox, but why is the answer 0%? Shouldn't it be "there is no answer" or "paradox"? Either way, great teaser. | |

I thought that as well, Viper. 50%. Hmmm... :-? :-? | |

Oops! #9 does not belong in there. It just snuck in when I was not looking. | |

Pretty easy, but enjoyed it. | |

The correct answer should be among the options for answering. | |

I chose to not answer this question at random. | |

It seems that if I choose to answer the question at random and do answer the odds that I've correctly answered are 100% (sure thing). Just sayin'! | |

Posted by Zykezex | 01/06/14 |

Isn't the odds of choosing A or D 33.333...% (one out of three) 25%, 50%, 60%? | |

Posted by Zykezex | 01/06/14 |

I mean 33.333% choosing A or D and being correct... | |

Posted by spikethru4 | 01/07/14 |

Zykezex: The probability of picking A or D is 2 out of 4, not 1 out of 3. Don't forget that "25%" is twice as likely as the other two options because it appears twice. FarFetched: That's the trick. If the "correct answer" were an option, you'd still get a paradox, e.g. What are the chances of picking the correct answer? A) 25% B) 50% C) 60% D) 25% E) 0% ...but clearly you can pick E 20% of the time so it's no longer correct. | |

Posted by Zykezex | 01/07/14 |

A thought: If I couldn't see the answers, A&D are 2/4. Having seen 25% twice, my choices narrowed to 1/3. (25%, 50% or 60%). The chances of being correct are still zero as 33.333% wasn't an answer for A or D. | |

Posted by spikethru4 | 01/09/14 |

That's a fair comment, but the point is you're answering at random, so the choices are (A, B, C, D), not (25%, 50%, 60%). | |

Wow...that's a great teaser! I love paradoxes |
