NCERT Class 12 Maths · Chapter 13 Probability · Exercise 13.2 Question 6
P(E)=3/5,P(F)=3/10,P(E∩F)=1/5. Are E,F independent?
💡 Concept Hints
- Define the events and identify which event is being conditioned on.
- Use P(E|F)=P(E∩F)/P(F), or separate the possible sources before applying total probability and Bayes.
✅ Step-by-Step Solution
Final Answer: No.
- The product of the marginals is (3/5)(3/10)=9/50.
- The supplied intersection is 1/5=10/50, which differs from that product.
