Hello, I posted this question last but I COULDN'T READ the person's writing. I couldn't tell which letter they listed for the answer I provided: a, b, c, d, or e.

Please redo this answer more clearly showing the chosen letter.

Let f (x, y) = 2 sin( x2 + y2  ) / x2 + y2 for all (x, y) does not equal (0, 0). Define f (0, 0) in order to make f continuous at (0, 0).

a. None of these

b. f (0, 0) = 1

c. f (0, 0) = 0

d. Not possible

e. f (0, 0) = 2

I need solution and formula as clear.Otherwise , I will have to report the answer. Assume that X and Y has a continuous joint p.d.f. as 28x2y3 in 0<y<x<1 interval. Otherwise the joint p.d.f. is equal to 0. Prove that the mentioned f(x,y) is a joint probability density function. Calculate E(X) Calculate E(Y) Calculate E(X2) Calculate E(XY)
