A recent SURVEY of 100 households in the hobby-farm area of Hinterwalden produced the following results about vehicle ownership: 73 households admitted owning a car. 70 households admitted owning a TRUCK. 48 said they owned both a car and a truck. No household admitted to owning more than one truck or more than one car. At a recent meeting of the Concerned Truck-Driving Citizens of Hinterwalden, a spot CHECKof the car-park showed that there were 38 trucks but no cars. For the purposes of this question, assume that every truck in the car-park belonged to a Hinterwalden household and that the vehicle's occupants were attending the meeting. Answer the questions below. Round all your answers to four decimal places: Given that each truck in the car park comes from a household that owns a truck, what is the probability that a randomly selected truck in the car park comes from a household that does not also own a car? What is the probability that at least 15 of the trucks in the car park come from households that do not also own cars? Given that each truck in the car park comes from a household that owns a truck, what is the probability that no more than half of the trucks in the car park come from households that also own cars? ....provide with simple understandable solution.
