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? (enter your answer as a fraction.)

Firsrt, find the total number of people that you can draw overall. To do this, add the number of people on campus and the number of people off campus to get 24 people overall. This will be your denominator. Then, the numerator is the number of the group of people that the question is asking for. In this case, it would be the 4 people off campus. Finally, put in the values to get that the probability is
