In an expert system database, a rule is defined as: (P1 AND P2) OR P3 ⇒ R1 (0.8) and R2 (0.3), where P1, P2, and P3 are premises, and R1, R2 are conclusions with rule certainty factors (CF) of 0.8 and 0.3 respectively. If a running program has established P1, P2, and P3 with certainty factors of 0.5, 0.8, and 0.2 respectively, find the absolute certainty factors of the results derived from these premises using typical certainty logic propagation rules.

- 1CF(R1) = 0.8, CF(R2) = 0.35
- 2CF(R1) = 0.15, CF(R2) = 0.35
- 3CF(R1) = 0.40, CF(R2) = 0.15✓
- 4CF(R1) = 0.8, CF(R2) = 0.3
Correct answer
CF(R1) = 0.40, CF(R2) = 0.15
