Poisson Distribution

P(X = X|) = e^x/x!

where

P(X = x|) = probability that X = x events in an area of opportunity given

= expected number of events per unit

e = mathematical constant approximated by 2.71828

x = number of events (x = 0, 1, 2, . . .)

1.Let = 5.0, find P(X 2).(Round to three decimal places)

2.Let = 0.4, find P(X 1).(Round to three decimal places)

3.Let = 4.0, find P(X 3).(Round to three decimal places)

4.Let = 3.8, find P(X 2).(Round to three decimal places)

5.Let = 5.5, find P(X 2).(Round to three decimal places)
