CUET Mathematics - A farmer has a tubewell which works by connecting two switches S_1 and S_2. The probability that S_1 works is 9/10 and the probability that S_2 works is 8/10. The farmer connects them in series in 30% cases and in parallel in 70% cases. If it is known that the tubewell was working, what is the probability that it was a series connection. | PYQs + Solutions
