Question: A car dealership has combined all popular options available in four packages. The first three packages have the same chance of being sold and the fourth package is twice as likely to be sold as any one of the other packages. If package 1, package 2, and package 4 contain a CD player, find the probability that a randomly selected car will be sold with a CD player. Now assume that five different customers have ordered cars independently, what is the probability that at least 3 CD players will be ordered?
