Question

Consider a Poisson distribution with μ = 4. If needed, round your answer to four decimal digits.

(b)	Compute f(2).

(c)	Compute f(1).

(d)	Compute P(x ≥ 2).

Answer 1

Let, X follows Poisson distribution with = 4 then probability mass function is,

      , x = 0 , 1 , 2 , .............

a) We have to find f(2)

                  { Using Excel,   =EXP(-4) = 0.018316 }  

b) We can to find f(1)

c) We have to compute P(x >= 2 )

From part b, f(1) = 0.0733
