Three persons A, B and C attended a recruitment test. The ratio of the chances of \(A, B, C\) in getting through the test \(1: 2: 3\) and their probabilities to face the interview successfully are \(0.8,0.7,0.6\) respectively. If one of them is to be selected for the post, then the probability that \(\mathrm{A}\) gets the post is
- A \(\frac{3}{8}\)
- B \(\frac{7}{20}\)
- C \(\frac{9}{20}\)
- D \(\frac{1}{5}\)
Answer & Solution
Correct Answer
(C) \(\frac{9}{20}\)
