I need help with a homework problem on binomial distribution. Twenty percent of American households own three or more vehicles? You choose 12 households at random. What is the probability that none of the chosen households owns three or more vehicles? What is the probability that at least one household owns one or more vehicles. I remember the n over k. I believe it is 12 over 0 but i don't remember how to do the rest of the problem?
