NAWNCO. Figuring out the rules is pretty much the whole game, so, have at it.

One Rapper Likes Big Butts and Cannot Lie; One Rapper Likes Small Butts and Always Lies

with 4 comments

Donkeylicious celebrates nineteen years of Sir Mix-a-Lot with a novel logic puzzle.

You are curious whether your butt is big or small. Unfortunately, you lack the ability to accurately assess the size of butts. Fortunately, there are three rappers before you who can accurately assess the size of your butt. You are of their preferred gender, so they are willing to collectively entertain exactly one yes-or-no question from you, to which they will each give an answer.

One rapper likes big butts and cannot lie. One rapper likes small butts and always lies. One rapper likes all butts but shares your inability to assess butt size, and will answer yes or no at random if asked whether a butt is big or small. You do not know which rapper is which. All the rappers know all other facts relevant to the situation, including everyone’s identity and butt preferences.

Before you are able to ask your question, one rapper receives a booty call (the size of the booty is unknown to you) and leaves the room. The other two rappers remain and are willing to pronounce on your question. You still do not know who any of the rappers are.

To determine the size of your butt, what question should you ask them? (You may assume that all butts can be classified as either big or small and ignore contextual factors, e.g. from the presence of Oakland booty.)

In a country in which people only want boys every family continues to have children until they have a boy. If they have a girl, they have another child. If they have a boy, they stop. What is the proportion of boys to girls in the country?

I more or less spent my day taking every possible position on every possible variation on this question. Is there any way I can get my Sunday back?

Late night!

* Still more logic puzzles, via the comments.

* My father directs our attention to a disturbing provision in North Carolina state law.

* I mean, we just went from winter to spring. In Missouri when we go from winter to spring, that’s a good climate change. I don’t want to stop that climate change, you know. Yglesias uses this inanity to try and make a serious point, but man. That’s the second-stupidest thing ever said about climate change.

* Michael Pollan or Michel Foucault?

Friday night in Albuquerque.

* Today in tasers: 72-year-old grandmother Tasered for refusing to sign a speeding ticket. New York judge allows Tasering to force compliance with DNA test. The system is working as intended; obviously these are both cases where lethal force would have been necessary in the absence of a Taser. (Via MeFi.)

* The Memory Card covers iconic moments from classic video games. Also via MeFi.

* Remembering Tiananmen.

* ‘Graveyard Civiizations’: The idea here is that we can explain the Fermi paradox (’Where are they?’) by assuming that exponential growth is not a sustainable development pattern for intelligent civilizations.
