I'm posting one puzzle, riddle, math, or statistical problem a day. Try to answer each one and post your answers in the comments section. I'll post the answer the next day. Even if you have the same answer as someone else, feel free to put up your answer, too!
At a movie theater, the manager announces that a free ticket will be given to the first person in line whose birthday is the same as someone in line who has already bought a ticket. You have the option of getting in line at any time. Assuming that you don't know anyone else's birthday, and that birthdays are uniformly distributed throughout a 365 day year, what position in line gives you the best chance of being the first duplicate birthday?
The rebus are back again. If you look carefully, you can see the words or common phrases hidden in the arrangement of letters and words below. For example, the title represents West Indies (West in D's).
In the most recent Biggest Loser competition, the contestants had to arrange the order of five dishes from least calories to most. If they did it blind-folded, how many different ways could the food be arranged?
But let's say they have some knowledge about a couple of the dishes. They know the plate of hamburger (loaded with everything) and chips should be near the top, while the plate of broccoli should be near the bottom of the scale. How does that affect the number of choices?
5 children in this puzzle had a bowl of cereal for breakfast with one drink and another bowl of cereal (different than breakfast) as an after-school snack.
The children were:
Dean, Emma, Julia, Patrick, Thomas
The cereals were:
Brownies, Cococrunch, Crumbler, Krispo & Wheeties
The drinks were:
Coffee, Milk, Orange Juice(OJ), Tea & Water.
1.The child who ate Wheeties for breakfast had a bowl of Krispo after school.
2.Emma wasn’t the child who drank coffee in the morning & ate a bowl of Brownies in the afternoon
3.The child who drank a glass of water with his/her Brownies at breakfast time is either Patrick of Thomas
4.Emma didn’t eat Cococrunch or Crumbler for breakfast
5.The child who had a glass of milk ate Cococrunch for breakfast, but not Crumbler as an after-school snack
6.Patrick drank either milk or tea for breakfast.
7.The child who drank coffee (decaf!) didn’t eat a bowl of Crumbler for breakfast.
8.Dean (who never drinks coffee) didn’t have a bowl of Crumbler for his breakfast.
