Tell Your Friend
left border "There are 20 squares of tile on the floor of the candy store. The clerk dropped a jar of jellybeans. I will show you the picture of the jellybeans on the floor -- but only for 2 seconds. You will have a stack of cards that shows the number of beans on each square. Pick any 3 cards and use them to estimate the total number. You win if your estimate is within 10 jellybeans of the total."

Try this with several friends and keep track of their answers. There are 120 jellybeans total.
