This project was one of the simpler projects we did. It involved throwing a pair of dice 100 times and graphing and analyzing the frequency distribution of the sum of the numbers that came up on the dice. This project investigated the mathematics of probability, and required a lot less equipment and data points than most of our other science fair projects.

We found that the sum of two dice was unlikely to be very low (2 or 3) or very high (11 or 12), but was most likely to be close to the middle of the possible range (5, 6, or 7). The graph looked like a pyramid, as shown below.

When you analyze the mathematics of probability, it is very easy to explain why our results came out this way. This is a good experiment to do if you like math and want a project that is simple to do and doesn't require a lot of time and equipment.

We decided to put up a web page about our project so that maybe someone else will do a similar project for their science fair or get some ideas from what we did. If you want to know all about the project, you'll want to download a copy of our report. It is a 1.3 MB PDF file, so you can read it on any type of computer. You will need Acrobat Reader to read it (get it here if you don't already have it). Then click this link to download our report.
