In a game, a man wins Rs. 5 for getting a number greater than 4 and loses Rs. 1 otherwise, when a fair die is thrown.
The man decides to throw the die thrice but quits as soon as he gets a number greater than 4 .
The expected value of the amount (in Rs.) he wins or loses is :
- A \(\frac{14}{9}\)
- B \(\frac{19}{9}\)
- C \(\frac{22}{9}\)
- D \(\frac{25}{9}\)
Answer & Solution
Correct Answer
(B) \(\frac{19}{9}\)
Step-by-step Solution
Detailed explanation
\(P(\text{Win}) = P(\text{number} > 4) = \frac{2}{6} = \frac{1}{3}\) \(P(\text{Lose}) = P(\text{number} \le 4) = \frac{4}{6} = \frac{2}{3}\)…
