Given that x has a Poisson distribution with Mu 11 what s t

Given that x has a Poisson distribution with Mu = 1.1, what ?s the probability that x = 4? P(4) (Round to four decimal places as needed)

Solution

mean = U = 1.1

x = 4

The formula is :

P(x) = (u)^x * e^(-u) / x!

P(x = 4) = (1.1)^4 * e^(-1.1) / 4!
