NCERT Class 12 Maths · Chapter 13 Probability · Exercise 13.1 Question 16
If P(A)=1/2, P(B)=0, 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: C: not defined.
- The elementary definition divides P(A∩B) by P(B).
- Since P(B)=0, the denominator vanishes; no conditional value is determined by this definition.
