错选、多选或未选均无分。

1.A. AB. BC. CD. D答案：B解析：A,B互为对立事件,且P(A)＞0,P(B)＞0,则P(AB)=0P(A∪B)=1，P(A)=1-P(B),P(AB)=1-P(AB)=1.2.设A，B为两个随机事件，且P（A）>0，则P（A∪B｜A）=（）A. P（AB）B. P（A）C. P（B）D. 1答案：D解析：A,B为两个随机事件,且P(A)＞0,P(A∪B|A)表示在A发生的条件下,A或B发生的概率,因为A发生，则必有A∪B发生，故P(A∪B|A)=1.3.下列各函数可作为随机变量分布函数的是（）A. AB. BC. CD. D答案：B解析：分布函数须满足如下性质：（1）F(+∞)=1,F(-∞)=0,(2)F(x)右连续,(3)F(x)是不减函数,(4)0≤F(x)≤1.而题中F1(+∞)=0；F3(-∞)=-1；F4(+∞)=2.因此选项A、C、D中F(x)都不是随机变量的分布函数,由排除法知B正确,事实上B满足随机变量分布函数的所有性质.4.设随机变量X的概率密度为A. AB. BC. CD. D答案：A5.设二维随机变量（X，Y）的分布律为(如下图)则P{X+Y=0}=（）A. 0.2B. 0.3C. 0.5D. 0.7答案：C解析：因为X可取0,1,Y可取-1,0,1,故P{X+Y=0}=P{X=0,Y=0}+P{X=1,Y=-1}=0.3+0.2=0.5.6.设二维随机变量（X，Y）的概率密度为A. AB. BC. CD. D答案：A7.设随机变量X服从参数为2的泊松分布，则下列结论中正确的是（）A. E（X）=0.5，D（X）=0.5B. E（X）=0.5，D（X）=0.25C. E（X）=2，D（X）=4D. E（X）=2，D（X）=2答案：D解析：X~P(2),故E（X）=2，D（X）=2.8.设随机变量X与Y相互独立，且X~N（1，4），Y~N（0，1），令Z=X-Y，则D（Z）=（）A. 1B. 3C. 5D. 6答案：C解析：X~N(1,4),Y~N(0,1),X与Y相互独立,故D(Z)=D(X-Y)=D(X)+D(Y)=4+1=5.9.A. 0.004B. 0.04C. 0.4D. 4答案：C10.A. AB. BC. CD. D答案：B二、填空题（本大题共15小题，每小题2分，共30分）请在每小题的空格中填上正确答案。
