another density question

hi folks: here's another density question. x ~ U(a,b) y ~ U(c,d) where 0 < a < c < b < d. what is density of 1. z = min(x,y) 2. w = y - z i'll appreciate it if you can give me some pointers. i did some matlab simulations and my results show that 1. z is uniform between [a,c], jumps up at c a

i wrote a little code in matlab that figures out the density of z = x*y where x and y are both uniformly distributed. in the code i wrote, x and y are distributed over the same range and my results show a funky looking triangular distribution with the mode/mean/median in the middle. is this corre
