Although cities encourage carpooling to reduce traffic congestion, most vehicles carry only one person. For example, nationally 75.5% of the people drive to work alone.
(a)if you choose 12 vehicles at random, what is the probability that more than half(that is, 7 or more) carry just one person?)create a probability distribution table and a cumulative distribution.
(b)if you choose 80 what is the probability that more than half(that is,41 or more) carry just one person?), provide the graph as your answer, do not use the normal approximation here.
