In a study of vehicle ownership, it has been found that 31% of U.S. households do not own a vehicle, with 50% owning 1 vehicle, and the remaining owning 2 or more vehicles. The data for a random sample of 207 households in a resort community are as follows:

70 owned 0 vehicles, 101 owned 1 vehicle, and the remaining owned 2 or more vehicles.
