1.) Two donuts. Take three donuts on one side and three donuts on the other side and see if any of the sides are heavier. If none of the sides are lower then the other side, the donut that is heavier is on the scale. Then take the two donuts that are not on the scale and measure them both. If one is heavier then you found the donut that is the heaviest. Therefore you can only measure two at a time.
2.) I think if you roll snake eyes two times in a row, you might have a 50-50 chance of rolling them again. Unless the dice is loaded, meaning set to go on a certain point or number.
3.) To flip the triangle upside down but only be able to move three pennies, you would need to flip only the top penny and the bottom two pennies. You would put the two bottom pennies to the top of the triangle, and bring the top one down.
4.) You would have to put the squares on the outer layer but all together you would have 12 squares. The black squares are smaller then the white ones are bigger.
5.) There should be 96 games played in all, because at least one team will lose one game against each other.
