Question 1049526: According to a local survey 80% of Americans own a car. If you randomly select 3 Americans
(a) What is the probability that all of them own a car?
P(All own a car) =
80
(b) What is the probability that none of them own a car?
P(None own a car) =
(b) What is the probability that at least one them owns a car?
P(At least one owns a car) =

You can put this solution on YOUR website! p(owning a car) = .8,
n = 3
P(All own a car) = P(x=3) = binompdf(3,.8,3)= .512 0r (.8)^3
P(None own a car) = P(x = 0) = binompdf(3,.8,0)= .008 0r (.2)^3
P(At least one owns a car) = 1 - P(x = 0)= 1-.008 = .992
