If m is a mean of Poisson distribution then P(X=0) is given by
B) en-m
С) е
OD 0​

Answer 1

Answer:

Answer: aExplanation: For a discrete probability function, the mean value or the expected value is given byMean(μ)=\sum_{x=0}^n xp(x)For Poisson Distribution P(x)=\frac{e^{-m}m^x}{x!} substitute in above equation and solve to get µ = m = np.
