NCERT Class 12 Maths · Chapter 13 Probability · Exercise 13.1 Question 2
Compute P(A|B) if P(B)=0.5 and P(A∩B)=0.32.
💡 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: 16/25=0.64.
- Use P(A|B)=P(A∩B)/P(B).
- Substitute 0.32/0.5=32/50=16/25.
