Riddle: The Upsherin Turn

Four three-year-old Jewish boys, Reuven, Shimon, Levi and Yehuda, come to Meron for their first haircut. They are each asked to select a kippa from among two blue ones and two white ones. The boys do not see what color kippa they have chosen, but Reuven can see Shimon’s and Levi’s, Shimon can see Levi’s and Levi and Yehuda can’t see anyone’s. What are the odds that Reuven will be the first to positively know the color of his own kippa and why?

Solution: Reuven has a 50% chance of being first to be able to positively identify his color.

There is a 50% chance that both Shimon and Levi will end up with an identically colored kippa, and in that case, Reuven will know that his kippa must be the other color. If however, Shimon and Levi each end up with a different colored kippa, then after a short time, Shimon will deduce that since Reuven has not identified his color kippa, it must be that his color kippa is different from Levi and so he will be able to identify his color first.

Last Month’s Junior Riddle: Takeout Madness

Morris ordered three hamburgers from the deli, but only one with onions. Each hamburger was packed in a separate bag with a different colored sticker. The one with the blue sticker says “onions”, the one with the yellow sticker says “the burger with the blue sticker has no onions”, and the one with the red sticker says “no onions”. The clerk tells Morris that that at least two of the stickers are wrong. How can Morris figure out which burger has onions without opening the bags.

Solution: The onions must be in the bag with the red sticker, because if it were in any other bag, at least two stickers would be correct.
