Q1. In a knowledge base, a rule is defined as (P1 and P2) or P3 → R1 (0.8) and R2 (0.3), where P1, P2, P3 are premises and R1, R2 are conclusions of the rule with certainty factors (CF) 0.8 and 0.3 respectively. If a running program has produced P1, P2, P3 with CF 0.5, 0.8 and 0.2 respectively, find the CF of the results on the basis of the premises.
- CF(R1) = 0.8, CF(R2) = 0.3
- CF(R1) = 0.40, CF(R2) = 0.15
- CF(R1) = 0.15, CF(R2) = 0.35
- CF(R1) = 0.8, CF(R2) = 0.35

Q99. Given below are two statements:
Statement I: "A grandparent is a parent of one's parent."
Statement II: The first-order predicate logic (FOPL) representation of the above statement is ∀g, c grandparent(g, c) ⇔ ∃p parent(g, p) ∧ parent(p, c).
Choose the most appropriate answer.
Statement I: "A grandparent is a parent of one's parent."
