Karnataka, Tamil Nadu and Kerala, respectively. Also given that the losses are inde

pendent. The Moment Generating Functions of X, Y, Z are given, respectively by

Mx(t) = (1 - 21)-3

My(t) = (1

21)-25

Mz(t) = (1-2t)-4.5

Let S represent the combined loss from these three states. Calculate E(S).
