Question 744330
Recent information published by the U.S. Environmental Protection Agency indicates that Honda is the manufacturer of four of the top nine vehicles in terms of fuel economy.
-----
Binomial condition with p = 4/9
-----------
a. Determine the probability distribution for the number of Hondas in a sample of three cars chosen from the top nine.
P(x = 0 hondas) = (5/9)^3
P(x = 1 honda) = 3C1(4/9)(5/9)^2
P(x = 2 hondas) = 3C2(4/9)^2(5/9)
P(x = 3 hondas) = (4/9)^3
===================================

b. What is the likelihood that in the sample of three at least one Honda is included?
P(at least one) = 1 - P(none)
= 1 - (5/9)^3
