Self-referential statements can lead to paradoxes, so one could say the question is not well-formed because it is self-referential.
If, as mentioned, choice (C) were 0%, and options (A),(B),(D) were unchanged, then the question leads to a paradox. If choice (D) were 50%, and options (A), (B), (C) were unchanged, then both 25% and 50% would be consistent answers --so (A), (B) and (D) would all be defensible (but, obviously, they cannot all be correct). As it stands the answer appears to be 0% since every choice leads to a contradiction, but I would prefer the answer that the question is not well-formed. ________________________________________ From: friam-boun...@redfish.com [friam-boun...@redfish.com] On Behalf Of Carl Tollander [c...@plektyx.com] Sent: Saturday, October 29, 2011 12:08 PM To: The Friday Morning Applied Complexity Coffee Group Subject: Re: [FRIAM] [sfx: Discuss] Fwd: FlowingData - Best statistics question ever Imagine it's not multiple choice...

Like the Monty Hall, I'd like to hear a pro reason through to the answer.
