The probability that Kabir clears an interview is (2/5)
and the probability that Simran fails is (1/4). Find the probability that both have the same result if both appear.Solution
Probability that Kabir fails = 1 - (2/5) = (3/5)
Probability that Simran passes = 1 - (1/4) = (3/4)
Required probability = (2/5) Ă— (3/4) + (3/5) Ă— (1/4)
= (6/20) + (3/20) = (9/20)
