For that question: how a probability event becomes to be a certainty event after some time.The answerer is that the Probability is changing along the development of time since many factors will affect the Probability in that time interval and Probability=1 at the point it happened.

Based on the flaw of the probability reliability model in the case of small amount of information,non-probability and mixed probability/non-probability reliability models are presented. When the uncertainty of the basic random variable is described by convex, analytical and numerical methods are constructed to calculate the convex of response variable. The infinite norm index, which is the minimal infinite norm distance from original coordinate point to the surface of the limit state in the standard interval space, is presented to measure the safety of the structure.

An impossible event has a probability of exactly 0, and a certain event has a probability of 1, but the converses are not always true: probability 0 events are not always impossible, nor probability 1 events certain.

一个'不可能'事件其机率值为0，而'确定'事件其机率值则为1。但反推并不成立，也就是说机率值为0的事件不表示它就是一个'不可能'事件，同理，机率值为1的事件不表示它就一定发生。

An ''impossible'' event has a probability of exactly 0, and a ''certain'' event has a probability of 1, but the converses are not always true: probability 0 events are not always impossible, nor probability 1 events certain.

但反推并不成立，也就是说机率值为0的事件不表示它就是一个'不可能'事件，同理，机率值为1的事件不表示它就一定发生。
