CBSE Class 12 Mathematics 2026 Main Paper 65(B) · Question 16 (Probability)
If P(A | B)=P(B | A) and P(A∩B)>0, what follows?
✅ Step-by-Step Solution
Final Answer: P(A)=P(B)
- The common positive intersection can be cancelled from the two conditional-probability formulas. Without its positivity the printed implication fails.
