May 14 exercise for exam P

I have posted a new exercise for exam P:

This is in response to questions raised by some concerning transformations of random vectors, and sums of random variables, convolution and derivation of the PDF of the result of those operations. The exercise is given with three different solutions, showing three different approaches you can use for sums or differences of random variables: transformation of random vectors, convolution, or the CDF technique. It may feel a bit hairy, but it is meant to show you all of these techniques and help you deal with this kind of problems in every possible way. I hope you will enjoy.

Yours,
