Hi
  Poisson Distribution:  4.7 bags/day
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus

 Find the probability that, on a given day:
(a) The airline looses exactly eleven bags. P(x=11) = .0056

(b) The airline looses fewer than nine bags. P(x≤ 9) = .9778

(c) The airline looses more than nine bags. 1- P(x≤ 9) = 1 - .9778 = .0222
