One roll of the dice would tell you very little, but the more times you rolled them, the more data you collected, the more confident you would become, not just whether they're loaded or fair, but by how much, and in what way.
滚一次骰子，你得到的信息很有限。 但滚越多次， 你收集到的信息就越多， 你对自己的判断就越有信心。 不仅是这些骰子是否平整， 而且是平整的程度，哪里不平整等， 你都了如指掌。
