若随机变量,,则Φ(-1)=,Φ(1)=. /ananas/latex/p/569761/ananas/latex/p/1338074
举一反三
- 若随机变量XN(u,),则P(X>a)=1-P(Xa)/ananas/latex/p/173/ananas/latex/p/3922/ananas/latex/p/1237
- 已知向量组 ,,, 若 ,, 线性相关,则t=./ananas/latex/p/1207466/ananas/latex/p/1207483/ananas/latex/p/1207493/ananas/latex/p/1390/ananas/latex/p/2677/ananas/latex/p/56537
- 若 且满足,则/ananas/latex/p/1077893/ananas/latex/p/121860/ananas/latex/p/1077899
- 证明:若函数在内满足关系式 且 则/ananas/latex/p/209239/ananas/latex/p/534180/ananas/latex/p/534181/ananas/latex/p/534182/ananas/latex/p/534183
- 已知()=0.4,则()=( )/ananas/latex/p/152/ananas/latex/p/278/ananas/latex/p/847/ananas/latex/p/281/ananas/latex/p/152/ananas/latex/p/4781/ananas/latex/p/7419/ananas/latex/p/6547
