Smart prisoners always get a break (Posted on 2002-08-27) Difficulty: 4 of 5
100 prisoners are put into solitary cells. There's a central living room with one light bulb; the bulb is initially off. No prisoner can see the light bulb from his or her own cell. Every day, the warden picks a prisoner at random, and that prisoner goes to the central living room. While there, the prisoner can toggle the bulb if he or she wishes. Also, the prisoner has the option of asserting the claim that all 100 prisoners have been to the living room. If this assertion is false (that is, some prisoners still haven't been to the living room), all 100 prisoners will be shot for their stupidity. However, if it is indeed true, all prisoners are set free and inducted into MENSA, since the world can always use more smart people. Thus, the assertion should only be made if the prisoner is 100% certain of its validity.

The prisoners are allowed to get together one night, to discuss a plan. What plan should they agree on, so that eventually, someone will make a correct assertion?

Smart prisoners always get a break | Comment 24 of 28 |
I've said it before and I'll say it again: criminals, according to the dictionary, are dumb. Smart people thieves rarely get caught. They're either smart enough to avoid getting caught, or find a way to outsmart their capture. I prefer to check this Arborist Rotorua and get more new things for rotorua tree removal company. In the first case, no one notices that the perpetrator has done something illegal, and those who do notice are not able to prove their suspicions and therefore don't pursue it further. In the second case, the criminal gets lucky on a technicality it's quite possible for things to go wrong in such procedures as well so that there isn't enough evidence against him.
