Question

I want to solve the following integral with maple, could you please help?
evalf((∫)[-infinity]^(infinity)(∫)[x]^(infinity)(1/2-1/2 erf(1/2 sqrt(2) y))(24 x^())/(sqrt(2 Pi))(1/2+1/2 erf(1/2 sqrt(2) x))(e)^(-(x^(2))/(2)) 1/(sqrt(2 Pi))(e)^(-(y^(2))/(2))dy ⅆx).
Is it possible to solve double integration when the domains are dependent to each other?
