Two events E and F are independent. If \(P ( E )=\frac{3}{5}\) and \(P ( F )=\frac{3}{10}\) then \(P \left( E ^{\prime} / F \right)+ P \left( F ^{\prime} / E \right)=\) ___________ .
- A \(\frac{1}{10}\)
- B \(\frac{11}{10}\)
- C \(\frac{9}{10}\)
- D \(\frac{10}{11}\)
Answer & Solution
Correct Answer
(B) \(\frac{11}{10}\)
Step-by-step Solution
Detailed explanation
\(P(E') = 1 - P(E) = 1 - \frac{3}{5} = \frac{2}{5}\) \(P(F') = 1 - P(F) = 1 - \frac{3}{10} = \frac{7}{10}\)
