Problems

Select a Logic Problem from the choices below.

Create a new page (name the new page with your First Name), and use it to describe your answer and how you arrived at it. Explain the logic you used to arrive at your answer! (I'm trusting you NOT to cheat and look at someone else's page to get the answer!)

Then, go to another student's solution page and add your opinion of whether you they their answer is correct. If you think they are wrong, explain why.

Problem 1. Really Easy!
 * Cathy has six pairs of black socks and six pairs of white socks in her drawer.
 * In complete darkness, and without looking, how many socks must she take from the drawer in order to be sure to get a pair that match?

Problem 2. Still Pretty Easy!
 * Mary's mum has four children.
 * The first child is called April.
 * The second May.
 * The third June.
 * What is the name of the fourth child?

Problem 3. Getting More Difficult.
 * Four tasmanian camels traveling on a very narrow ledge encounter four tasmanian camels coming the other way.
 * As everyone knows, tasmanian camels never go backwards, especially when on a precarious ledge. The camels will climb over each other, but only if there is a camel sized space on the other side.
 * The camels didn't see each other until there was only exactly one camel's width between the two groups.
 * How can all camels pass, allowing both groups to go on their way, without any camel reversing?

Problem 4. Really Tough! I Dare You to Try This One!
 * Cannibals ambush a safari in the jungle and capture three men. The cannibals give the men a single chance to escape uneaten.
 * The captives are lined up in order of height, and are tied to stakes. The man in the rear can see the backs of his two friends, the man in the middle can see the back the man in front, and the man in front cannot see anyone. The cannibals show the men five hats. Three of the hats are black and two of the hats are white.
 * Blindfolds are then placed over each man's eyes and a hat is placed on each man's head. The two hats left over are hidden. The blindfolds are then removed and it is said to the men that if one of them can guess what color hat he is wearing they can all leave unharmed.
 * The man in the rear who can see both of his friends' hats but not his own says, "I don't know". The middle man who can see the hat of the man in front, but not his own says, "I don't know". The front man who cannot see ANYBODY'S hat says "I know!"
 * How did he know the color of his hat and what color was it?
