For independent X and Y, we have probability density function for them where pdf of X is f(x) = ne^-nx and pdf of Y is f(y) = me^-my. (x and y greater than 0). Let M1=max(X,Y) and M2=min(X,Y). Find cov(M2,M1).

For this problem we have two charge distributions: an infinite charge plane at z = -6m with surface charge density of pS and an infinite line of charge with linear charge density of pL = 3 μC / m passing through points A (3m, 4m, 0) and B (-3m, -4m, 0). to. (20 pts) Draw a picture of the two load distributions indicated above. Indicate axes and values clearly.
The joint probability density function of X and Y is given by f(x,y)=c(y2−16x2)e−y, −y4≤x≤y4, 0
