Let represent the probability mass function of a Poisson distribution. If its mean then value of at which is maximum is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(B)
Step-by-step Solution
Detailed explanation
We know that the Poisson distribution is given by px=e-λλxx! where, x=0, 1, 2, 3, 4 Since, e-λ is a positive constant therefore it is sufficient to find the maxima of λxx!. Now, when x=0⇒λxx!=1 Now, we have to find maxima of…
