A bag contains four balls. Two balls are drawn randomly and found them to be white. The probability that all the balls in the bag are white is
- A \(\frac{1}{2}\)
- B \(\frac{3}{5}\)
- C \(\frac{1}{4}\)
- D \(\frac{2}{3}\)
Answer & Solution
Correct Answer
(B) \(\frac{3}{5}\)
Step-by-step Solution
Detailed explanation
Let the events are \(E\) : Two drawn balls are white; \(E_1\) : All balls are white \(\mathrm{E}_2: 3\) white balls and 1 other; \(\mathrm{E}_3: 2\) balls white and 2 others…
