Web2. 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 ... WebBoth, really. A theorem known as the Central Limit Theorem states that the distribution of the sum of independent random variables tends towards a normal distribution. This result is why things tend to be approximately normally distributed, particularly in mean estimates (as the mean is a form of sum). crystal mn wikipedia

SD = 150. z = 230 ÷ 150 = 1.53. The z score for a value of 1380 is 1.53. That means 1380 is 1.53 standard deviations from the mean of your distribution. Next, we can find the probability of this score using a z table. dxb to trv flight rate
