A bag contains 6 balls. If three balls are drawn at a time and all of them are found to be green, then the probability that exactly 5 of the balls in the bag are green is:
- A \(\frac{4}{35}\)
- B \(\frac{5}{35}\)
- C \(\frac{2}{7}\)
- D \(\frac{1}{7}\)
Answer & Solution
Correct Answer
(C) \(\frac{2}{7}\)
Step-by-step Solution
Detailed explanation
Let \(A\) be the event we draw three green balls. Let \(B\) be the event that fine balls are green. Let \(E_1\) be event that there are 3 green balls. \(E_2\) be event that there are 4 green balls. \(E_3\) be event that there are 5 green balls. \(E_4\) be event that there are 6…
