CASE STUDY

College Driver Insurance offers discounted auto insurance to college students. Background The company uses several factors to set discounts, as follows:

 • A student who has taken a safe driver course earns a 5% discount. 

• A student with a clean record (no tickets or accidents in the last three years) earns a 5% discount.

 • A student who is 23 or older earns a 5% discount.

 • A student who meets all three conditions (has taken a safe driver course and has a clean record and is 23) earns an additional bonus discount of 5%. 

Tasks 

1. Create a decision table that describes the discount rules.

 2. Simplify the table you just created. Describe the results. 

3. Draw a simplified decision tree that shows the discount rules. 

4. What are the pros and cons of using a decision table versus a decision tree?
