A man has a goat, a wolf and a head of cabbage. He comes to a river and must bring these three things across to the other side. The boat can only take the man plus either the goat, wolf, or cabbage. He can make as many trips as he needs to. There is another problem. If the cabbage is left with the goat, the goat will eat the cabbage, If the wolf is left with the goat, the goat will be devoured.
How can he successfully transport the wolf, the goat and the cabbage to the other side?
