概率论期末复习试题二

概率论期末复习试题二

概率论与数理统计试题11级计算机大队二区队一、选择题:1、假设事件A与事件B互为对立,则事件AB( )。

(A) 是不可能事件(B) 是可能事件(C) 发生的概率为1 (D) 是必然事件答案:A。

这是因为对立事件的积事件是不可能事件。

2、某人睡午觉醒来,发现表停了,他打开收音机想听电台整点报时,则他等待的时间小于 10分钟的概率是()。

A、16B、112C、160D、172答案:A。

以分钟为单位,记上一次报时时刻为0,则下一次报时时刻为60,于是,这个人打开收音机的时间必在(0,60)内,记“等待时间短于分钟”为事件A。

则有S=(0,60), A=(50,60)所以P(A)=AS=1060=16。

3、设连续型随机变量(X,Y)的两个分量X和Y相互独立,且服从同一分布,问 P{X≤Y}=()。

A、0B、12C、14D、1答案:B。

利用对称性,因为X,Y独立同分布,所以有P{X≤Y}=P{Y≤X},而P{X≤Y}+ P{Y≤X}=1,所以P{X≤Y}=1 24、设二维随机变量(X,Y)的分布函数为F(x,y),分布律如下:则F(2,3)=()。

A、0B、14C、716D、916答案:D 。

F(2,3)=P{X≤2,Y≤3}=P{X=1,Y=1}+P{X=1,Y=2}+ P{X=1,Y=3}+ P{X=2,Y=1}+ P{X=2.Y=2} + P{X=2,Y=3}=14+0+0+116+14+0X Y 1 2 3 41 140 0 1162 116140 143 0 116116=9165、下列命题中错误的是( )。
