An actuary has done an analysis of all policies that cover two cars. 70% of the policies are of type A for both cars, and 30% of the policies are of type B for both cars. The number of claims on different cars across all policies are mutually independent. The distributions of the number of claims on a car are given in the following table.
Number of Claims Type A Type B
0 40% 25%
1 30% 25%
2 20% 25%
3 10% 25%
