23. In a large population of drivers the accident rate A of a randomly se- lected person varies from person to person according to a I'(2,10) ran- dom variable. If X|[AA] is the number of accidents a person with accident rate A incurs in a year, then assume X | [AA] is a Poisson random variable with parameter A. If X represents the number of ac- cidents a randomly selected person has in a year, what are E(X) and Var(X)?
