CBSE Class 12 Mathematics 2026 Main Paper 65/5/3 · Question 8 (Probability)

The printed data say 3P(A)=P(B)=3/5 and P(A | B)=2/3. Which listed union value does formal substitution give, and are the data consistent?

✅ Step-by-Step Solution

Final Answer: 2/5
  1. Formal substitution gives P(A∩B)=2/5 and union 1/5+3/5−2/5=2/5. But P(A∩B)>P(A), so no actual events satisfy the printed data.
