Let x denote the size of a bodily injury claim and y denote the size of the corresponding property damage claim. let z1 = x + y. from prior experience we know var(x) = 144, var(y) = 64 and var(x + y) = 308. it is expected that bodily injury claims will rise 10% next year and property damage will rise by a fixed amount of 5. let z2 be the new trial of bodily injury and property damage. compute cov(z1, z2 ).
