Rope Burn Riddle
You have two ropes. Each rope takes one hour to burn. These ropes are not identical, nor are they uniform; i.e. it does not necessarily take half an hour for half the rope to burn (if you have trouble visualizing this, imagine a rope of varying thickness across its length). With only these two ropes and a way to light them, how do you measure out 45 minutes?
Hint: You can light multiple ends and/or multiple ropes at the exact same time.
Light both ends of one rope, and only one end of the other rope. This will cause the first rope to burn out in 30 minutes. When the first rope burns out, there will be 30 minutes left on the second rope. So then, light the other end of the second rope, and the rest of it will burn out in 15 minutes. 30 + 15 = 45 minutes.

Fox Rabbit Cabbage
A merchant has a fox, a rabbit, and a head of lettuce and sits on the edge of a river. He has a small raft capable of carrying only himself and one item at a time, but without his supervision the fox will eat the rabbit, and the rabbit will eat the lettuce. How can he successfully transport all goods from one side of the river to the next without losing the lettuce or rabbit? The dilemma, of course, is true regardless of which side of the river they are on and there is no other way across.
Hint:
First the farmer takes the rabbit across and returns to the fox & cabbage. Next, the farmer takes the cabbage, but when he arrives to the other side with the rabbit, he leaves the cabbage and takes the rabbit back on the raft with him to return and get the fox. He exchanges the rabbit for the fox and returns to drop the fox off with the cabbage, and finally goes back to get the rabbit. Did you answer this riddle correctly?

Three Rats Riddle
Three rats are sitting at the three corners of an equilateral triangle. Each rat starts randomly picks a direction and starts to move along the edge of the triangle. What is the probability that none of the rats collide?
Hint:
So lets think this through. The rats can only avoid a collision if they all decide to move in the same direction (either clockwise or rati-clockwise). If the rats do not pick the same direction, there will definitely be a collision. Each rat has the option to either move clockwise or rati-clockwise. There is a one in two chance that an rat decides to pick a particular direction. Using simple probability calculations, we can determine the probability of no collision.
