I hope I wrote that correctly but I'm trying to find the joint. I heard it was impossible from someone.
X = A/R A~BIN(n1, p1) R~BIN(n2, p2) I know I shouldn't be using the Jacobian method for Discrete distributions but I have to do it anyway. Anyone know?

The major difficulty arises from the fact that P(R=0) > 0, so you have a nonzero probability of X being infinite.
