4.6-JG-3Random variable, W, is formed as the sum of independent random variables such that W=X+Y where the density functions of X and Y are: fx(x)=u(x-1)-u(x-2) and fy(y)=0.4d(x-1)+0.6d(x-1.5) (where "d" stands for delta function). Give sketches of fx(x), fy(y), and fw(w). Ans: fw(w)=0.4u(x-2)+0.6u(x-2.5)-0.4u(x-3)-0.6u(x-3.5).
