NCERT Class 12 Maths · Chapter 13 Probability · Exercise 13.2 Question 17
Find the probability of an even prime number on each of two fair dice.
💡 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: D: 1/36.
- The only even prime is 2, so the event is exactly the ordered pair (2,2).
- There are 36 equally likely pairs, giving 1/36.
