Just For Fun


Suppose you are traveling with a fox, a goose and a mouse when you come to a large river. The only way to cross the river is with a raft that holds at most you and one animal. Furthermore, if left unattended by you, the fox will eat the goose and the goose will eat the mouse. How many trips in the raft will it take to get you and your three pets across the river (alive)?
