数学期望是随机变量最重要的特征数之一，它是消除随机性的主要手段.本文通过对数学期望的概念、性质以及应用性的举例，下面是我为你整理的数学期望应用毕业论文，一起来看看吧。
摘要：数学期望是随机变量的重要数字特征之一，也是随机变量最基本的特征之一。通过几个例子，阐述了概率论与数理统计中的教学期望在生活中的应用，文章列举了一些现实生活实例，阐述了数学期望在经济和实际问题中颇有价值的应用。
关键词：随机变量，数学期望，概率，统计
数学期望(mathematical expectation)简称期望，又称均值，是概率论中一项重要的数字特征，在经济管理工作中有着重要的应用。本文通过探讨数学期望在经济和实际问题中的一些简单应用，以期起到让学生了解知识与人类实践紧密联系的丰富底蕴，切身体会到“数学的确有用”。
1.决策方案问题
决策方案即将数学期望最大的方案作为最佳方案加以决策。它帮助人们在复杂的情况下从可能采取的方案中做出选择和决定。具体做法为：如果知道任一方案Ai(i=1，2，…m)在每个影响因素Sj(j=1，2，…，n)发生的情况下，实施某种方案所产生的盈利值及各影响因素发生的概率，则可以比较各个方案的期望盈利，从而选择其中期望盈利最高的为最佳方案。
投资方案
假设某人用10万元进行为期一年的投资，有两种投资方案：一是购买股票;二是存入银行获取利息。买股票的收益取决于经济形势，若经济形势好可获利4万元，形势中等可获利1万元，形势不好要损失2万元。如果存入银行，假设利率为8%，可得利息8000元，又设经济形势好、中、差的概率分别为30%、50%、20%。试问应选择哪一种方案可使投资的效益较大?
[摘 要] 离散型随机变量数学期望是概率论和数理统计的重要概念之一，是用概率论和数理统计来反映随机变量取值分布的特征数。通过探讨数学期望在经济和实际问题中的一些简单应用，以期让学生了解数学期望的理论知识与人类实践紧密联系，它们是不可分割、紧密联系的。
[关键词] 数学期望;离散型随机变量
一、离散型随机变量数学期望的内涵
在概率论和统计学中，离散型随机变量的一切可能的取值xi与对应的概率P(=xi)之积的和称为数学期望(设级数绝对收敛)，记为E(x)。数学期望又称期望或均值，其含义实际上是随机变量的平均值，是随机变量最基本的数学特征之一。但期望的严格定义是∑xi*pi绝对收敛，注意是绝对，也就是说这和平常理解的平均值是有区别的。一个随机变量可以有平均值或中位数，但其期望不一定存在。
二、离散型随机变量数学期望的作用
期望表示随机变量在随机试验中取值的平均值，它是概率意义下的平均值，不同于相应数值的算术平均数。是简单算术平均的一种推广，类似加权平均。在解决实际问题时，作为一个重要的参数，对市场预测，经济统计，风险与决策，体育比赛等领域有着重要的指导作用，为今后学习高等数学、数学分析及相关学科产生深远的影响，打下良好的基础。作为数学基础理论中统计学上的数字特征，广泛应用于工程技术、经济社会领域。其意义是解决实践中抽象出来的数学模型进行分析的方法，从而达到认识客观世界规律的目的，为进一步的决策分析提供准确的理论依据。
三、离散型随机变量的数学期望的求法
离散型随机变量数学期望的求法常常分四个步骤：
1.确定离散型随机变量可能取值;
2.计算离散型随机变量每一个可能值相应的概率;
3.写出分布列，并检查分布列的正确与否;
4.求出期望。
四、数学期望应用
(一)数学期望在经济方面的应用
例1： 假设小刘用20万元进行投资，有两种投资方案，方案一：是用于购买房子进行投资;方案二：存入银行获取利息。买房子的收益取决于经济形势，若经济形势好可获利4万元，形势中等可获利1万元，形势不好要损失2万元。如果存入银行，假设利率为，可得利息11000元，又设经济形势好、中、差的概率分别为40%、40%、20%。试问应选择哪一种方案可使投资的效益较大?
第一种投资方案：
购买房子的获利期望是：E(X)=4××(--2)×(万元)
第二种投资方案：
银行的获利期望是E(X)=(万元)，
由于：E(X)>E(X)，
从上面两种投资方案可以得出：购买房子的期望收益比存入银行的期望收益大，应采用购买房子的方案。在这里，投资方案有两种，但经济形势是一个不确定因素，做出选择的依据是数学期望的高低。
(二)数学期望在公司需求方面的应用
例2：某小公司预计市场的需求将会增长。公司的员工目前都满负荷地工作。为满足市场需求提高产量，公司考虑两种方案 ：第一种方案：让员工超时工作;第二种方案：添置设备。
假设公司预测市场需求量增加的概率为P，当然可能市场需求会下降的概率是1―P，若将已知的相关数据列于下表：
市场需求减(1-p) 市场需求增加(p)
维持现状(X)
20万 24万
员工加班(X)
19万 32万
耀加设备(X)
15万 34万
由条件可知，在市场需求增加的情况下，使员工超时工作或添加设备都是合算的。然而现实是不知道哪种情况会出现，因此要比较几种方案获利的期望大小。用期望值判断：
E(X)=20(1-p)+24p，E(X)=19(1-p)+32p，E(X)=15(1-p)+34p
分两种情况来考察：
(1)当p=，则E(X)=(万)，E(X)=(万)，E(X)=(万)，于是公司可以决定更新设备，扩大生产;
(2)当p=，则E(X)=22(万)，E(X)=(万)，E(X)=(万)，此时公司可决定采取员工超时工作的应急措施扩大生产。
由此可见，从上面两种情况可以得出：如果p=时，公司可以决定更新设备，扩大生产。如果p=时，公司可决定采取员工超时工作的应急措施。因此，只要市场需求增长可能性在50%以上，公司就应采取一定的措施，以期利润的增长。
(三)数学期望在体育比赛的应用
乒乓球是我们得国球，全国人民特别爱好，我们在这项运动中具有绝对的优势。现就乒乓球比赛的赛制安排提出两种方案：
第一种方案是双方各出3人，三局两胜制，第二种方案是双方各出5人，五局三胜制。对于这两种方案， 哪一种方案对中国队更有利?不妨我们来看一个实例：
假设中国队每一位队员对美国队的每一位队员的胜率都为55%。根据前面的分析，下面我们只需比较两队的数学期望值的大小即可。
在五局三胜制中，中国队若要取得胜利，获胜的场数有3、4、5三种结果。我们应用二项式定律、概率方面的知识，计算出三种结果所对应的概率，恰好获得三场对应的概率：;恰好获得四场对应的概率：;五场全胜得概率：.
设随机变量X为该赛制下中国队在比赛中获胜的场数，则可建立X的分布律： X 3 4 5
P
计算随机变量X的数学期望：
E(X)=3×××
在三局两胜制中，中国队取得胜利，获胜的场数有2、3两种结果。对应的概率为=;三场全胜的概率为=。
设随机变量Y为该赛制下中国队在比赛中获胜的场数，则可建立Y的分布律：
X 2 3
Y
计算随机变量Y的数学期望：
E(Y)=2××
比较两个期望值的大小，即有E(X)>E(Y)，因此我们可以得出结论，五局三胜制中国队更有利。
因此，我们在这样的比赛中，五局三胜制对中国队更有利。在体育比赛中，要看具体的细节，具体情形，把握好比赛赛制，用我们所学习的知识来实现期望值的最大化，做到知己知彼，百战百胜。
(四)数学期望对企业利润的评估
在市场经济活动中，厂家的生产或是商家的销售.总是追求最大的利润。在生产过程中供大于求或供不应求都不利于获得最大利润来扩大再生产。但在市场经济中，总是瞬息万变，往往供应量和需求量无法确定。而厂家或商家在一般情况下根据过去的数据，再结合现在的具体情况，具体对象，常常用数学期望的方法结合微积分的有关知识，制定最佳的生产活动或销售策略。
假定某公司计划开发一种新产品市场，并试图确定其产量。估计出售一件产品，公司可获利A元，而积压一件产品，可导致损失B元。另外，该公司预测产品的销售量x为一个随机变量，其分布为P(x)，那么，产品的产量该如何制定，才能获得最大利润。
假设该公司每年生产该产品x件，尽管x是确定的.但由于需求量(销售量)是一个随机变量，所以收益Y是一个随机变量，它是x的函数：
当xy时，y=Ax;
当xy时，y=Ay--B(x-y)。
于是期望收益为问题转化为：
当x为何值时，期望收益可以达到最大值。运用微积分的知识，不难求得。
这个问题的解决，就是求目标函数期望的最大最小值。
(五)数学期望在保险中问题
一个家庭在一年中五万元或五万元以上的贵重物品被盗的概率是，保险公司开办一年期五万元或五万元以上家庭财产保险，参加者需缴保险费200元，若在一年之内， 五万元或五万元以上财产被盗，保险公司赔偿a元(a>200)，试问a如何确定，才能使保险公司期望获利?
设X表示保险公司对任一参保家庭的收益，则X的取值为 200或 200�a，其分布列为：
X 200 200-a
p
E(x)=200×(200-a)×>0，解得a<40000，又a>100，所以a∈(200，40000)时，保险公司才能期望获得利润。
从上面的日常生活中，我们不难发现：利用所学的离散型随机变量数学期望方面的知识解决了生活中的一些具有的，实实在在的问题有大大的帮助。
因此我们在实际生活中，利用所学的离散型随机变量数学期望方面的知识，面对当今信息时代的要求，我们应当思维活跃，敢于创新，既要学习数学理认方面知识，更应该重视对所学知识的实践应用，做到理认联系实际，学以致用。当然只是实际生活中遇到的数学期望应用中的一部分而已，还有更多的应用等待我们去思考，去发现，去探索，为我们伟大的时代创造出更多的有价值的东西和财富。

The Advantages of Top University
Nowadays, some students believe that entering a top university is not that necessary, because some of the successful businessmen like the Alibaba’s founder Ma Yun and QQ’s founder Ma Huateng have nothing to do with the top university. Actually, top university have its own advantages. First, you can meet the excellent people there. The friends you make maybe your business partners in the future and the teachers are with higher level, which can pass you the advanced konwledge. Second, though the textbooks for every university are almost the same, but top university teaches students with different methods. It pays attention to cultivate students with critical minds and pratical ability. The thesis is very strict for students, when they pass it, they will cry with happiness, because they are admitted by the professors. When the students graduate from top university, they have made a different.
如今,一些学生认为进入一所顶尖大学学习并不是必要的,因为一些成功的商人像阿里巴巴的创始人马云和QQ的创始人马化腾都与顶尖大学无关。实际上,顶尖大学有自己的优势。首先,你可以在那里遇到优秀的人。你的朋友也许是你将来业务的合作伙伴，而且老师更高的水平,这可以传授你先进的知识。第二,尽管每个大学的教科书几乎相同,但顶尖大学教学生用不同的方法。它注重培养学生批判性思维和实际能力。论文对学生要求很严格,当他们通过了,会幸福地哭起来,因为他们得到了教授的承认。当学生从顶尖大学毕业的时候,他们已经有所作为。
very girl loves fashion, when they see the models walking on the stage, they will be attracted and want to follow their styles. Most girls start to notice the fashion as they become the teenagers, when they are children, they don’t see the difference. But it has been reported that a four years old girl had created the fashion. What the shocking news, the girl is from America and she can design the dress by herself, the paper is the main material. The mother said that the girl loved to see fashion show and then she would make the dress to imitate the style. The mother posted the pictures on the Internet, and soon it caught many people’s attention, people spoke highly of the girls’ design. Her talent was noticed by the famous company, they signed her and let the girl make her own style. What a talented girl.
每个女孩都喜欢时尚,当她们看到模特走在舞台上时,会被吸引,想要追随的她们风格。大多数女孩在青少年时期才开始注意到时尚,当她们还是孩子的时候,不会区别时尚。但是据报道,一个四岁女孩创造了时尚。多么令人震惊的消息,这个女孩来自美国,她可以自己设计衣服,纸是主要的材料。妈妈说女孩喜欢看时装表演,然后她会模仿风格去制作衣服。母亲在互联网上发布了图片,很快就引起了很多人的注意,人们高度评价了女孩的设计。她的才华被著名的公司看中,他们签了她,让这个女孩制作自己的风格。这是一个多么有才华的女孩啊。
The high school life is never easy for me. On one hand, I have to learn so many subjects, for the purpose of entering a good university. On the other hand, I am so afraid of lagging behind other students. I always feel like I am in the competition and sometimes I want to get away from this situation. When I am tired, I try not to think about the study, I will go to the cinema and watch a movie. Losing in the movie can help me forget about the annoyance and laugh out loudly. Sometimes I will ask my friends to go to the restaurant, buffet is my favorite. Eating all kinds of food and we play some fun games is also a good way for me to be happy. When I am back, I will be full of energy and fight for my future.
我的高中生活从来都不容易。一方面,我必须学习很多科目,为了进入一个好的大学。另一方面,我很害怕落后于其他同学。我总是感觉我在竞争,有时我想要摆脱这种情况。当我累了,我试着不去想学习,我将会去看电影,看电影。失去的电影可以帮助我忘记烦恼和大声笑了出来。有时候我会问我的朋友去餐厅,自助餐是我的最爱。吃各种各样的食物,我们玩一些有趣的游戏也是一个好方法让我很高兴。当我回来,我将充满能量和为我的未来而战。
大学英语四级考试(CET-4)是衡量大学生英语水平的重要指标,同时与学位证书挂钩,受到师生的广泛关注。下面是我带来的英语四级 文章 原文及翻译，欢迎阅读!英语四级文章原文及翻译篇一 Talent Show Nowadays, talent shows have occupied a good proportion of screen time. Participants compete in various fields, such as singing, acting and cat walking, etc. The winners not only get grand prix but also gain promising career prospects in the entertainment industry. People hold diversified opinion about talent shows. According to a survey conducted in X city, 59% of the interviewees believed that they did more good than harm, whereas 41% opposed it. 现在，选秀节目占据了电视播出时间的很大一部分。参与者在各个领域竞争，比如 唱歌 、表演、走猫步等等。获胜者不仅能得到大奖，而且能在娱乐界获得很有前途的职业前景。人们对选秀有各种各样的看法。根据在X市所做的调查，59%的受访者相信选秀是利大于弊，然而有41%的人表示反对。 The people in favor of the shows believe that they have given participants an equal chance to bring forth their talents. Talent shows in general provide a platform for people who want to stand in the spotlight. Besides, such programs are usually interactive with audience who vote out the winners. Despite the economic gains, many people dislike such contests, holding that the vulgar competition encourages an unhealthy thinking among the young people of becoming famous ovemight. 支持选秀的人认为它们给参赛者一个平等的展示天分的机会。选秀节目通常为那些想站在聚光灯下的人提供一个平台。此外，这种节目一般会与观众互动，由观众投票选出获胜者。尽管经济在增长，有许多人不喜欢这种比赛，他们认为低俗的比赛助长了年轻人中想一夜成名的不健康想法。 In my opinion, talent shows are no doubt a commercial success and an entertainment feast. And it is all too easy to label them as "vulgar" or "biased". Though I do have some reservation towards them, I believe that the programs themselves are not harmful， as long as run properly and viewed with a light heart of enjoyment. (206 words) 我认为，选秀节目无疑是个商业上的成功和娱乐盛宴。而且给它们贴上“低俗”或“有偏见”的标签太草率了。虽然我确实对它们有一些异议，但我相信只要合理操作并且用欣赏的轻松心态来看待，节目本身没有害处。 英语四级文章原文及翻译篇二 A Letter of Apology 15th , March Dear Mr. Wang, I am writing to apologize for my late homework.

It's taken me this long to understand that the cookie will never make me happy for long. 不同的是，他只有两岁半，而我已经 43 了。我花了这么长的时间才明白小甜饼并不能使我长久感到幸福。 The minute you have the cookie it starts to crumble or you start to worry about it crumbling or about someone trying to take it away from you. 从你拥有小甜饼的那一刻，它就开始破碎，或者你就开始担心它会破碎，抑或你开始担心别人拿走它。 You know, you have to give up a lot of things to take care of the cookie, to keep it from crumbling and be sure that no one takes it away from you. 为了守护你的小甜饼，为了防止它破碎或者确定别人不会从你手中夺走它，你不得不放弃许多东西。 You may not even get a chance to eat it because you are so busy just trying not to lose it. 你忙于不让自己失去它，甚至没有时间享受它。 Having the cookie is not what life is about." My patient laughs and says cancer has changed him. 拥有小甜饼并不是生活的全部内容。”我的病人笑着说癌症已经改变了他。 For the first time he is happy. No matter if his business is doing well or not, no matter if he wins or loses at golf. " 不论他的生意是否一帆风顺，不论他在打高尔夫球时是输是赢，他有生以来第一次感到幸福。 Two years ago, cancer asked me, 'Okay, what's important? What is really important?' Well, life is important. “两年前，癌症问我‘什么重要?什么才真正的重要?’对，生命重要。 Life. Life any way you can have it, life with the cookie, life without the cookie. Happiness does not have anything to do with the cookie; it has to do with being alive. Before, who made the time?" He pauses thoughtfully. "Damn, I guess life is the cookie." 生命。生命，无论如何你拥有生命。有小甜饼也罢，没有小甜饼也罢，幸福与小甜饼并非息息相关，而是与生命的存在有关。可是，时光一去不复返，谁又能让时光倒流呢?”他停顿了一下，若有所思，说：“该死，我觉得生命就是那块小甜饼”。 大学英语美文摘抄带翻译：人如孤岛 How wonderful are islands!

When the noise stops there is no inner music to take itsplace. We must relearn to be alone. 这其实仅仅是 _个填补空缺的问题，一旦暄闹消失，便不再有内心的音乐来填 补空缺。我们要重新学会孤独。 大学英语美文摘抄带翻译：一直走在阳光里 Years of storms had taken their toll on the old windmill. Its wheel, rusted and fallen, lay silent in the lush bluegrass. Its once animated silhouette was now a tall motionless steeple in the twilight sun. 多年的风雨毁坏了古老的风车。车轮已经锈了，倒了，静静地躺卧在茂盛的六月禾丛中。在落日的衬托下，曾经散发着生气的风车如今如耸立的尖塔般冰冷、生硬。 I hadn‘t walked across our old farm in fifteen years.

She always made me *** ile, even after Sis and I had just had a big squabble. I would help Greta with her chores. Then we would visit over a generous helping of her delicious homemade chocolate cookies and ice cream. Being confined to a wheel chair didn‘t stop Greta from being a fabulous cook. 无论雨天或晴天，我曾经天天沿着这条小径去探望葛丽塔。即使我刚和姐姐大吵了一场，她也总能使我舒怀微笑。我会帮葛丽塔做些家务。然后，我们会大快朵颐，品尝她亲手做的巧克力曲奇饼和冰淇淋。以轮椅代步并不妨碍她成为一名出色的厨师。 Greta gave me two of the greatest gifts I‘ve ever received. First, she taught me how to read. She also taught me that when I forgave Sis for our squabbles, it meant I wouldn‘t keep feeling like a victim. Instead, I would feel sunny. Mr. Dinking, the local banker, tried to foreclose on Greta‘s house and land after her hu *** and passed away. Thanks to Pa and Uncle Johan, Greta got to keep everything. Pa said that it was the least he could do for someone talented enough to teach me to read! 在葛丽塔的丈夫去世后，当地的银行家丁肯先生曾经要收取她抵押给了银行的房子。幸亏有爸爸和约翰叔叔的帮忙，葛丽塔才保住了一切。爸爸说，对一位聪明得能教会我认字的人，这只是他力所能及的一件小事! Soon folks were ing from miles around to buy Greta‘s homemade cakes, pies, breads, cookies, cider, and ice cream. Hank, the grocery store man, came each week to stock his shelves and bring Greta supplies. 很快，方圆数英里的人们都来买葛丽塔做的蛋糕、馅饼、面包、曲奇饼、苹果酒和冰淇淋。每周，杂货店老板汉克都会给她送来材料，并从她那里进货。 Greta even had me take a big apple pie to Mr. Dinking who became one of her best customers and friends.

When I ran into the old house, Greta recognized me right away. 这天，太阳刚下山我就来到葛丽塔家了。她门前几尺外已然停著一辆救护车。车上的红灯闪烁不停。当我冲入那所旧房子时，葛丽塔立刻认出了我. She *** iled at me with her unforgettable twinkling blue eyes. She was almost out of breath when she reached out and softly touched my arm. Her last words to me were "Dear, keep walking in sunshine!" 她冲我微微一笑，令人难忘的那双蓝眼睛闪著光芒。当她伸手轻抚我的手臂时，她已经奄奄一息了。她最后对我说的话是：“亲爱的，记得要走在阳光里!” I‘m sure that Greta is walking in the brightest sunshine she‘s ever seen. And, I‘m sure that she heard every word I read at her memorial service. 我肯定葛丽塔此时正漫步在她所见过的最明媚的阳光里。我也肯定她听见了我在她的追悼仪式上所念的每一个字。 I chose a beautiful verse by Leo Buscaglia. It‘s one that Greta taught me to read many years ago… 我选了利奥·巴斯卡格里亚的一首优美的诗，正是那首葛丽塔多年前教我念的诗。 "Love can never grow old. Locks may lose their brown and gold. Cheeks may fade and hollow grow. But the hearts that love will know, never winter‘s frost and chill, summer‘s warmth is in them still." “爱能历久常新。华发或会失去原有的光彩。双颊或会日显消瘦黯淡。然而，有爱的心中，从无寒冬霜冰，只有夏之温热。”
