¿ Riddles ?

You are one of three people in a duel to the death. You are standing at 12 o'clock in a giant circle. Duelist B stands at 4 o'clock and Duelist C stands at 8 o'clock. Each of you have pistols with unlimited ammo. You will be the first to fire a single shot. Then firing will continue one shot at a time in a clockwise fashion until there is only one person standing.

You are a horrible marksman with the probability of inflicting a fatal shot in 1 of 5 attempts. Duelist B is an average marksman with the probability of inflicting a fatal shot in 1 of 3 attempts. Duelist C is an excellent marksman with the probability of inflicting a fatal shot in 1 of 1 attempts.

You are not allowed to communicate with the other duelists.

Its your turn. Who do you fire at?

Answer

You are in a candle lit room with a single wooden door, no windows and three light switches labeled A, B and C. You cannot by any means see anything outside the room. The three switches are connected to three lights in another room. They are all currently in the off position.

You are given ten minutes in the room with the switches then you will be taken to the room with the lights. At that time you need to label each light with the letter of the corresponding switch.

How do you do it?
