Jack has a bag with an even number of gold coins of equal value and is surrounded by 6 pirates. If he does not give all of them equal gold coins(he can not keep any coin for himself) he dies, what is the probability that he LIVES?

Since he must divide the number of coins into six groups, the number of coins must be both a multiple of 2 and a multiple of three.

Since you know that there are an even number of coints, you already know that the number of coins is a multiple of two.

Therefore, for the number of coins to also be a multiple of three, there is a 1/3 probability that Jack survives.
