Main Question or Discussion Point
Hey,
I know how to find the expected value from the density function when it is in the form:
(example)
 y^2 1<y<1

fy =
 0 elsewhere
Ey = integral(upper limit 1, lower limit 1)[y*y^2 dy)
but, what if the density function looks like this:
 y^2 1<y<0

fy = y^2  y 0<y<1

 0 elsewhere
how do you approach here?
