*A large pool of adults earning their first driver's license includes 50% low-risk drivers, 30% moderate-risk drivers, and 20% high-risk drivers. Because these drivers have no prior driving record, an insurance com- pany considers each driver to be randomly selected from the pool. This month, the insurance company writes 4 new policies for adults earning their first driver's license.
