What is the first big change that American drivers made due to higher gas prices? According to a survey, 30% said that it was cutting recreational driving. However, 27% said that it was consolidating or reducing errands. If these figures are true for all Americans drivers, and if 20 such drivers are randomly sampled and asked what is the first big change they made due to higher prices, what is the probability that none of them said it was cutting recreational driving?
