Rolling A Dice. A fair rolling of dice is also a good example of normal distribution. In an experiment, it has been found that when a dice is rolled 100 times, chances to get ‘1’ are 15-18% and if we roll the dice 1000 times, the chances to get ‘1’ is, again, the same, which averages to 16.7% (1/6). If we roll two dice simultaneously ... 6 Real-Life Examples of the Normal Distribution. The normal distribution is the most commonly-used probability distribution in all of statistics.
