Question 907695
Eighty one percent of U.S. households have DVD players. Choose 6 households at random. What is the probability that at least one does not have a DVD player?
----------------
P(at least one does not have) = 1 - P(all have a DVD player)
--------------
P(at least one) = 1 - (0.81)^6 = 1 - 0.7176 = 0.2824
