Logic Problem One
You are at a picnic and there is a cooler full of juice. There are five apple juices, three grape juices, and three fruit punches. You really want an apple juice. Without looking at package of juice, what is the smallest number of juice packages that you need to take out of the cooler in order to make sure you get one apple juice. What is the smallest number if you really wanted fruit punch?
Logic Problem Two
From Raymond Smullyan's To Mock a Mockingbird
Suppose I offer one of three prizes: Prize A, Prize B, and Prize C. Prize A is the best prize. Prize B is an ok prize, and Prize C is the worst prize. If you say a true statement to me, for example, 2+2 = 4, I will give you prize A or B. If you say a false statement, I will give you Prize C. You really want Prize A. What could you say to me to force me to give you Prize A, the best prize.
