A box contains 10 mangoes out of which 4 are spoiled. 2 mangoes are taken together at random. If one of them is found to be good, then the probability that the other is also good, is
- A \(\frac{1}{3}\)
- B \(\frac{2}{3}\)
- C \(\frac{8}{15}\)
- D \(\frac{5}{13}\)
Answer & Solution
Correct Answer
(D) \(\frac{5}{13}\)
Step-by-step Solution
Detailed explanation
Let \(A\) be the event that the first mango is good and \(B\) be the event that second is good. \(\therefore\) Required probability \(=P\left(\frac{B}{A}\right)=\frac{P(A \cap B)}{P(A)}\)…
