suppose we have random variable defined a function of another random variable such that [tex] Y = \mathbb{E}(X) [/tex]
it seem then [tex] Y[/tex] is a constant. then [tex] \mathbb{E}(Y) = \mathbb{E}(X) [/tex] does this even make sense ?

If Y=E(X), then it is constant. Calling Y a random variable doesn't make sense. What is the context?
