Question
The probability that Riya passes the test is (4/9) and the
probability that Aditya fails is (1/3). If both appear for the test, find the probability that they both get the same result.Solution
Probability that Riya fails = 1 - (4/9) = (5/9)
Probability that Aditya passes = 1 - (1/3) = (2/3)
Required probability = (4/9) × (2/3) + (5/9) × (1/3)
= (8/27) + (5/27) = (13/27)
