please solve the problem and any missing data assumed that

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 |[A = X] is the number of accidents a person with accident rate A incurs in a year, then assume X | A = ] 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 )
