Re: Bafflers?

It is a toughie.


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.

Re: Bafflers?

Baffler #4

Batches of 15 steel balls are given to you. 14 of them are exactly alike. One ball is slightly heavier in each batch. You have a two pan balance that you can use to weigh the balls against each other. As the plant manager you are given the job of designing a method to find the heavier ball in each batch. Each weighing of any group of balls is considered one move. What is the average number of moves to determine the heavier ball for each batch?
