Background We wondered whether the probability of each roll will be equal to 0.16. Prof. Izumori advised that I should roll dice thirty-thousand times to investigate dice probability. So I decided to make automatic dice roller.
Commercially Available Dice shaker Fault: Dice come from wrong place Dice doesn’t always roll well
Thus, it can be expected that the more dots, the higher the frequency of rolling that side, and the less dots, the lower the frequency.
Assignment finish rolling dice 30,000 times and collecting data. improve Saikoron machine as a continuous experimental tool. verify the probability of those dice. examine the variation in the probability after changing the center of gravity of the dice.
