I am really stuck on how to work out this maths problem. Could someone give me a bit of guidance on how to get it started.
Let f(x1, x2) = 4x1x2, 0 < x1 < 1, 0 < x2 < 1,
= 0 elsewhere.
I need to find this below
P(x1 = x2)
That was the next question that we were given.
I have the answer to the question so I knew it was 0 but I do not know why.
For some reason we have limited information regarding this in our notes and as I have very limited statistical knowledge it is proving rather difficult to work out.
If you could give me a bit of guidance it would be very appreciated as I have an economics exam tomorrow!
