Project Notes

Thank you for viewing my probability project. First let me explain what theoretical and experimental are, in terms of probability. Theoretical is what should happen. The chance of rolling a one is, theoretically, 1/6 or 17%. Experimental is what actually happens, after you test something. If you roll a dice 6 times you should theoretically see 1 once. But really, you can see it any number of times. Now, the more times you roll the dice, the more your experimental results will match your theoretical results. If you roll it 6 times the results will be varied. If you roll it 600 times, the results will be about 100 for each number.



**Instructions**: First set how many times you want the dice to be rolled. Remember the more times you roll it, the more true to the theoretical chances it is. Then click the roll button. The dice will roll itself however many times you set it to. The number of times a face is rolled will appear below. Once the dice has finished rolling, click the Find Experimental Percentage button. It will then calculate the percentage. Theoretically, all faces should be 17%, but it will most likely be off. To do this process again click the Green Flag.
