The probability distribution of a random variable X is given by
| X | 0 | 1 | 2 |
| P(X) | k | 2k | 3k |
- A \(\frac{1}{6}\)
- B \(\frac{5}{6}\)
- C \(\frac{7}{8}\)
- D \(\frac{9}{16}\)
Answer & Solution
Correct Answer
(B) \(\frac{5}{6}\)
Step-by-step Solution
Detailed explanation
\(\sum P(X) = 1 \Rightarrow k + 2k + 3k = 1 \Rightarrow 6k = 1 \Rightarrow k = \frac{1}{6}\) \(P(0 \(P(0 < X \leq 2) = 5 \times \frac{1}{6} = \frac{5}{6}\)
