Rules

1. IF 'Temperature' IS 'Cold' AND 'Humidity' IS 'Dry'THEN 'Electric Roof' IS 'Closed' ALSO 'Water Spills' IS 'Moderate'
connective: AND (Minimum) ; implication: Product ; degree of support: 1.00

2. IF 'Temperature' IS 'Cold' AND 'Humidity' IS 'Normal'THEN 'Electric Roof' IS 'Closed' ALSO 'Water Spills' IS 'Less'
connective: AND (Minimum) ; implication: Product ; degree of support: 1.00

3. IF 'Temperature' IS 'Cold' AND 'Humidity' IS 'Wet' THEN'Electric Roof' IS 'Closed' ALSO 'Water Spills' IS 'Less'
