If the mean of a poisson distribution is \(\frac{1}{2}\), then the ratio of \(P(X=3)\) to \(P(X=2)\) is
- A \(1: 2\)
- B \(1: 4\)
- C \(1: 6\)
- D \(1: 8\)
Answer & Solution
Correct Answer
(C) \(1: 6\)
Step-by-step Solution
Detailed explanation
Given that \(\lambda=\frac{1}{2}\) Now, \(P(X=n)=\frac{\lambda^n}{n !} e^\lambda\)…
