Final answer:
To find the probability that a randomly selected student will be a junior, given that the student owns a car, you need to determine the number of students who are juniors and own a car, and divide it by the total number of students who own a car.
Step-by-step explanation:
To find the probability that a randomly selected student will be a junior, given that the student owns a car, you need to determine the number of students who are juniors and own a car, and divide it by the total number of students who own a car.
Let's say there are 100 students in total, and 40 of them own a car. If 20 of those car owners are juniors, then the probability would be 20/40 = 0.5, or 50%.
Therefore, the probability that a randomly selected student will be a junior, given that the student owns a car, is 0.5 or 50%
