ASSUME THE POISSON DISTRIBUTION APPLIES USE THE GIVEN MEAN T

ASSUME THE POISSON DISTRIBUTION APPLIES. USE THE GIVEN MEAN TO FIND THE INDICATED PROBABILITY. FIND P(4) WHEN U+3.

Solution

The formula for P(k) of the Poisson (mu) distribution is P(k) = exp(-mu) * (mu)^k / k!
Here, mu = 3 ; k = 4

Therefore,

P(4) = exp(-3) * (3)^4 / 4!
= 0.168 Answer
