事件概率

Born in London 1702, the son of a minister, Thomas Bayes developed a formula which allowed him to determine the probability of an event occurring based on the probabilities of two or more independent evidentiary events.

生于1702年的伦敦，一名部长的儿子，托马斯贝叶斯公式，使他形成了以确定一个事件发生的概率基于两个或两个以上的独立概率事件的证据。

The probabilities all possible risk incidents are very small. Even some incident appears it won't be destructive to the system.

所有可能发生的风险事件均属小概率事件，如有个别事件发生，也不会对系统构成毁灭性打击。

In Bayesian statistics, it can be seen as the posterior distribution of parameter p of a binomial distribution after observing α-1 independent events with probability p and β-1 with probability 1-p.

在贝叶斯统计，它可以被看作是后分布参数P一二项分布后，观测α-1独立事件的概率P和β- 1与概率1 - P的。

If a risk event has a chance of occurring 15 times out of 45 times, based on experiences with like events, what is the probability that the event will occur on the next project

如果一个风险事件的发生机会是45次中出现15次，基于类似事件的经验，在下个项目上，这个风险事件发生的概率是多少

Secondly, the combination in concept and problem teaching can enhance profound comprehension of Exclusive Events and Independent Events. Finally, because Distribution is basic knowledge in teaching probability, meanwhile, the calculation for Expected Value and Variance also are based on Distribution. Thus, Distribution is the most important in teaching them, it needs to give more emphasis.

其中计算机模拟手段在概率的频率定义教学中效果明显，并且直观模型在古典概型教学中的作用也相当明显；其次，通过概念教学与解题教学的结合可以帮助学生深刻理解互斥事件与独立事件；最后，随机变量的分布列作为概率基础知识，期望以及方差的计算都是以分布列为基础的，因而，强化分布列的教学是这部分内容的重中之重。

The main contents of the course is as follows: events and their probability, random variables and their distributions, moments, point estimation and interval estimation, hypothesis testing, etc.

课程的内容主要包括：事件与事件的概率；随机变量的概率分布与数字特征；参数的点估计；区间估计和假设检验等。

In this paper, data are transformed from data level to logic area level as the interpolation granularity.

为解决上述问题，首次将RFID数据从数据层抽象到逻辑区域层作为处理的粒度，提出3 种基于动态概率路径事件模型的数据填补算法，通过挖掘已知的区域事件的顺序相关性来对后续发生的事件进行判断

First, the physical meaning of the principle of preservation of probability is clarified, and the principle is then presented in terms of random event description and state space description, respectively.

文中首先剖析和澄清了概率守恒原理的物理意义，论述了概率守恒原理的随机事件描述和状态空间描述，并由此阐明了概率密度演化与系统物理演化的内在联系，即：系统的物理状态演化构成了概率密度演化的内在机制。

Through constructing the event tree for oil deport operation, this method can calculate the probability of the sequent event, find the risk index associated with the severeness of the sequent event, divid risk grade and put out risk alarm. so it can keep the accidents away efficiently.

该方法通过构造油库作业事件树，定量计算各后果事件的发生概率，并结合后果事件的严重程度确定风险指数，科学划分风险等级，发布相应风险警报，从而有效防范事故发生。

It is most likely that the common ancestor D also shared trait x. This is because of the Law or Principle of Parsimony - if two species share a trait, it is most likely that their common ancestor shared the same trait, and that events of evolutionary change are rare, and so you should postulate the minimum number of these events.

共同的祖先D也非常可能具有特点x，这是因为俭省原则--如果两个物种都具有一个特点，它们的祖先也非常可能具有这个特点，进化变化事件是非常少的，因此，你应该把这些事件假定为小概率事件。

Do not gum up the work by telling mother what we are going to do .

别告诉母亲我们要干的事，那会把事情搞糟的。

In recent years, application of the partial prestressed concrete beam s is developed.

近年来，随着部分预应力砼梁应用的推广，发现我国规范所采用的名义拉应力法的计算结果不稳定。
