In a Poisson distribution, μ = 4.80. (Round your answers to 4 decimal places.)
What is the probability that x = 0?
What is the probability that x > 2?
Poission distribution formula is
(A) To find :- P(X=0)
It is given that x = 0 and
this implies
(B) We can write because total probability is always 1
we have already calculated P(x=0) in above part, i.e. P(x=0) = 0.0082
and
It is given that x = 1 and for P(x=1)
this implies
Siimilarly,
setting P(x=0), P(x=1) and P(x=2) in first equation, we get
