设随机变量X~E(1),且,则P(Y≥2)= ./ananas/latex/p/837747
举一反三
- 设随机变量X~E(1),且,则P(Y≥2)= .
- 已知随机变量XN(µ,),且P(X≥2)=0.5,P(X≥5)=Φ(-1),则μ.../ananas/latex/p/3922
- 设X和Y为随机变量,且P{X0,Y0}=,则P{min(X,Y)<0}=/ananas/latex/p/990/ananas/latex/p/990/ananas/latex/p/36622
- 设随机变量,则P(2<X<3)等于()/ananas/latex/p/511542
- 设随机变量X服从参数为的泊松分布,且已知E[(X-1)(X-2)]=1,则/ananas/latex/p/479/ananas/latex/p/546408
