设事件E、F互斥,概率P(E)=p,P(F)=q,则P()是() ["A．q","B．1-q","C．p","D．1-p"]
已知矩阵满足方程=则x等于() ["A．0","B．3","C．1","D．4"]
自我介绍
程序 character*(*)name name=’apple’ L=len(name) Do10I=1,L 10name(I:I)=char(Ichar(name(I:I))+I print*,name end 程序运行后输出结果为() ["A．APPLE","B．brspj","C．jpsrb","D．apple"]
程序gramtraparea dataa,b/10,5/ y(x)=1*x+1 S=(y B．+yA．)*abc(b-a)/2 write(*,*)’S=’,S end 执行程序后,最接近S的值为() ["A．80.1","B．-80.0","C．90.5","D．70.1"]
在一次事件中，明明是顾客做错了，但顾客却一味认为是你错，你该怎么做?
