For the following joint probability density function, find the value of A, both marginal pdfs, and both conditional pdfs. Also, determine if X and Y are independent. Problem 8. Two random variables, x and y, are described by the following probability density function. Prove that this is a valid joint probability density function (pdf).

The estimation is made based on a finite number (n) of samples (training data): ~. The training data are independent and identically distributed (i.i.d.) generated according to some (unknown) joint probability density function (pdf) . Unknown function in (1) is the mean of the output conditional probability (a.k.a. regression function) (2)

The joint probability function (pdf) of the random variables (X,Y) is and zero otherwise. That is, the random variables X and Y are independent exponential random variables, each with parameter (. Find the joint probability function (pdf) of the random variables W=X and Z=X/Y. Be sure to include the range of the random variables in your answer.
