财女风情:投资彩票与中奖几率


财女风情:投资彩票与中奖几率
Created 09/10/2012 - 14:52
谁不想富有,谁不想过衣食无忧的生活?

只是每个人都想成为那微忽其微的幸运儿;这种侥幸的心态,助长彩票业迅猛发展。

这也是为什么中彩票几率那么低,以统计期望值来看几乎是必输的游戏,但是却可以风靡那么多人,算牌、签牌,包牌,什么怪招都来。

想让自己成为一个理性的理财赢家,到底该不该买彩票?

答案是不一定。

为什么?

一般来说,彩票的获利期望值为负数(因为政府要抽税、卖彩票的企业要抽佣),简单说,就是所有买彩票的人,当期的总支出一定会大于所得,完全听任几率决定胜负,你不可能用技术改善你的胜率。

所以,参加这样的赌局确实是不理智的行为,当然,有人相信他们可以用各种形式的算牌法来提高胜率,祝福他们能成功。

在我看来,你只是用钱买了做梦的特权,盘算着如何支配一笔在现实中你可能永远也不会得到的财富。

运气独立不会累计

几率里还有一个重要的概念,是事件的独立性概念。

很多时候,有人会因为前面已经有许多人没中奖而去买彩票,又或参与到累计回报的游戏;殊不知,每个人的“运气”都是独立的,不会因为前人没有中奖你中奖的机会就多了。

在这理,我不是想否定大家的美好梦想,只是要提醒你,投资彩票有超过50%的金额,其实就是你的“美梦成本”,只要能够认清这一点,爱怎么玩都随你,但后果自负。

假如真的幸运中奖了,那也请你一定要将奖金视为血汗钱,放进皮包里收好。

因为大多数中大奖的人很容易出现“财富麻痹症”,不知不觉就养成浪费的习惯,最后当彩金花光殆尽时,就会再度作可能再中奖的白日梦,那可真的是无药可救了!

中奖如同美丽梦想

什么是“彩票”?你弄懂了吗?

彩票是一种公益性的事业,怎能让多数人赚钱呢?

因为只要没有作弊,彩票纯粹就是几率的问题而已。确实,有的人买彩票,生活改善了,但你算过这其中的比率吗?

彩票从1000000号到1999999号,以100万为一组,共有01组到1000组的1000万种组合,这还是没数从2000000号到5999999号的组合。

你中奖的几率仍然近乎于零,这实在是很“美丽的梦想”!

尽管如此,我还是不建议你买彩票。

首先,你不是什么灵异之人,梦只是梦而已;其次,幸福研究表明,彩票赢家并没有因为中奖而变得更幸福。

但最重要的是,投资在彩票上的钱是很难回收的。在类似的博弈活动中,唯一确保以稳赚不赔的,大概只有主持的“庄家”而已。

当然,不管乐透彩、马票或21点,都是庄家精算过的赛局,可以投机的机会不多,因此有钱人不会在这上面花太多时间(要考虑赚钱的时间效率)。

实际上,彩票中奖的概率远比掷硬币,连续出现10个正面的“可能性”小得多。

买越多亏越多

如果你有充裕的空闲时间,不妨试试,拿一块硬币,看你用多长时间能幸运地掷出自始至终的连续10个正面。

实际上,每次抛掷时,你都“幸运”地得到正面的可能性是1/2,连续10次下来都是正面的概率是10个1/2相乘的总和,也就是(1/2)10=1/1024。

想想吧,千分之一的概率让你碰上了,难道不需要有上千次的辛勤抛掷做后盾?

所以理论上,彩票就是买越多损失越多的博弈游戏。一次买很多,存心要中头奖的人,几乎也都会通通拿去做“公益”了。

总结:赚大钱必辛劳

即使对追求金钱狂热,你也必须理性分析各种情况。

投资要求期望收益一定大于0,而博弈不要求,比如买彩票、赌马、赌大小……的期望收益就小于0。

支撑投资的是关于未来收益的分析和预测,而支撑博弈的是侥幸获胜心理;投资要求回避风险,而博弈是找风险。

所以,不论是博弈、投资或消费,对我们来说,最重要的是要充分理解金钱的流向和游戏的规则。

因此,在你尚未了解金钱的本质和游戏规则之前,我诚心地建议你不要轻易参与任何金钱游戏,如此才是真正的聪明之举!

创富的欲望及想赚钱的欲望是不同的;我得到一个重要的结论,就是太多人期待不劳而获,多数人只想要有钱花,而不太会去想怎样赚更多。

真的要赚钱,想赚大钱,从来没有不辛苦的。

与其把希望寄托在彩票上,不如寄托在自己身上。

生活的道路要踏踏实实地走,不要整日期待摇奖机给你摇出一条金光大道。对生活抱以认真的态度,生活也会赋予你美好的阳光!
