An automobile insurance company classifies applicants by their driving records for the previous three years. Let S = {applicants who have received speeding tickets}, A = {applicants who have caused accidents}, and D = {applicants who have been arrested for driving while intoxicated}. Describe the sets in Exercises 27-32 by using set-theoretic notation.
1. {Applicants who have not received speeding tickets}
2. {Applicants who have caused accidents and been arrested for drunk driving}
3. {Applicants who have received speeding tickets, caused accidents, or been arrested for drunk driving}
4. {Applicants who have not been arrested for drunk driving, but have received speeding tickets or have caused accidents}
5. {Applicants who have not both caused accidents and received speeding tickets but who have been arrested for drunk driving}
6. {Applicants who have not caused accidents or have not been arrested for drunk driving}
