Here's a good puzzle I heard recently. I'll credit the source later. I don't want anybody looking up the answer on the web-site. John Three gentleman, Alan,...
This one came up before. It's almost a thing of tactics and psychology as it is mathematics (like poker, and the dealer's offers in Deal Or No Deal). Carl's...

Hi Carl is the worst shooter. He makes one out of 3. He should never give a chance to alan for he is the best. He could give a chance to ben for he makes 2 out...
