Question
The probability that Ankit passes is (2/9) and the
probability that Shruti fails is (7/13). Find the probability that both have the same result.Solution
Probability that Ankit fails = 1 - (2/9) = (7/9)
Probability that Shruti passes = 1 - (7/13) = (6/13)
Required probability = (2/9) × (6/13) + (7/9) × (7/13)
= (12/117) + (49/117) = (61/117)
