In a class, 20 people live on campus and 4 people live off-campus. if we were to draw one student's name from a hat, what is the probability that this student is living off-campus?

Aflagpole broke in a storm. it was originally 8 1 81 feet tall. 2 8 28 feet are still sticking straight out of the ground, where it snapped, but the remaining piece has hinged over and touches the ground some distance away. how far away is the end of the pole from the base of the pole along the ground?
