NCERT Class 12 Maths · Chapter 13 Probability · Exercise 13.2 Question 1
If independent A,B have P(A)=3/5,P(B)=1/5, find P(A∩B).
💡 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: 3/25.
- Independence gives P(A∩B)=P(A)P(B).
- Multiply (3/5)(1/5)=3/25.
