Question
The probability that Dev clears the exam is (3/10) and the
probability that Kriti fails is (1/6). What is the probability that both of them have the same result?Solution
Probability that Dev fails = 1 - (3/10) = (7/10)
Probability that Kriti passes = 1 - (1/6) = (5/6)
Required probability = (3/10) × (5/6) + (7/10) × (1/6)
= (15/60) + (7/60) = (22/60) = (11/30)
