\int x f(x,y)dx

or

E[y]

\int y f(x,y)dy ?

example if f(x,y) = x+y

E[X] = \int x *(x+y)dx

The expected value would be:

[itex]

E[X] = \int_{0}^{1}\int_{0}^{1} x *(x+y)dxdy

= 7/12

[\latex]

Is that right?

Sorry,

[itex]

E[X] = \int_{0}^{1}\int_{0}^{1} x *(x+y)dxdy

= 7/12

[/itex]

[itex]

E[X] = \int_{0}^{1}\int_{0}^{1} x *(x+y)dxdy
