1. 7 weigh ins because if you have eight donuts and you put one on the scale and compare ever other donut to the one already on the scale you will figure which one is the heavy donut.
2. Same chances as when you rolled on your first time 1/36
3. If you have the pennies in a pyramid 4 on the bottom then 3 then 2 then 1. Take the top two tears that contains two pennies and 1 penny at the top and put it on the bottom so that the pyramid is reversed. Instead of it facing up it would face down.
4. There are many tiles in this problem and at least 1 white tile.
5. 48 games must be played and there is an extra team because it is an odd number and I don't know what to do with that
