The RiskEvaluator application assesses the risk of admitting a loan for a customer. It makes the decision upon four conditions, chosen by a client from the drop-down lists. The conditions are:
* age - possible answers:
- under 18
- between 18 and 35
- between 36 and 65
- over 65
* education - possible answers:
- elementary or high school
- undergraduate
- graduate
* place of living - possible answers:
- city
- village
If a client selects age "under 18", the field "education" is automatically filled with "elementary or high school" and the client is not able to change this value.
The output can be one of the following:
* Low risk
* Medium risk
* High risk
How many columns will have the decision table for this problem assuming that it contains only the feasible combinations of conditions?
Select one of the following:
