CBSE Class 12 Mathematics 2026 Main Paper 65/4/2 · Question 18 (Probability)

Rain probabilities in cities A, B and C are 60%, 70% and 80%. Assuming the three rain events are independent, find the probability of rain in at least one city.

✅ Step-by-Step Solution

Final Answer: 244/250
  1. Under independence the probability of no rain in all three cities is 0.4·0.3·0.2=0.024. The complement is 0.976=244/250.
