# 100 hat puzzle

100 prisoners stand in line, one in front of the other. Each wears either a red hat or a blue hat.

Starting at the back of the line, a prison guard asks each prisoner the color of their hat. If they answer correctly, they will be pardoned. Before lining up, the prisoners confer on a strategy to help them.

# Three cannibals and three anthropologists

Three cannibals and three anthropologists have to cross a river.The boat they have is only big enough for two people. The cannibals will do as requested, even if they are on the other side of the river, with one exception. If at any point in time there are more cannibals on one side of the river than anthropologists, the cannibals will eat them.

What plan can the anthropologists use for crossing the river so they don’t get eaten?

Note: One anthropologist cannot control two cannibals on land, nor can one anthropologist on land control two cannibals on the boat if they are all on the same side of the river. This means an anthropologist will not survive being rowed across the river by a cannibal if there is one cannibal on the other side.
